    The invention relates to a device for conditioning fuel to a gas turbine engine, the fuel comprising carbon monoxide and hydrogen. The fuel from an inlet passes through a reactor (11a-b) and the gas turbine engine is supplied with conditioned fuel from the reactor (11a-b). The reactor (11a-b) comprises catalyst (12) which combines the carbon monoxide and hydrogen into alcohols, which on combustion gives a lower NOX. In one embodiment, at least part of the fuel passes before it reaches the reactor (11a-b), one passage of a single-speed exchanger (10) which raises the temperature of the fuel and where the conditioned fuel from the reactor passes the second passage of the heat exchanger (10) before being fed to the gas turbine engine. This increases the efficiency of the catalyst. In a further embodiment, the reactor (11a-b) comprises cooling channels (27) which enable the temperature in the reactor to be controlled. In a variant, part of the fuel is fed to the cooling ducts and after-passage of the cooling ducts, it is fed to the part of the fuel which has passed the catalyst (12) of the reactor. In a second variant, water or water vapor is supplied to the cooling ducts and after passage of the cooling duct, the water or water vapor is supplied to the part of the fuel which has passed the second passage of the heat exchanger (10). The amount fl uid passing through the cooling ducts (27) can be controlled with input signals from a temperature sensor in the reactor (11a-b), so that the temperature in the reactor is optimized.

    composition. The formation of thermal NOX is more difficult to determine when fl your factors are involved.
    Thermal NOX is generated with a series of sequential reactions called the Zeldovích reactions after the person who recorded the reactions. The mechanism of the reactions is confirmed by accurate measurements. In summary, the reactions say that the formation of thermal NOX is an exponential function of the mans amman's temperature and a linear function of the time the temperature is maintained. In other words, temperature and residence time determine the level of thermal NOX emissions. These are mainly the two variables temperature and time available to control NOX emissions.
    The physical unit for quantifying NOX is "parts per million" (ppm) calculated as volume in the exhaust gases and after correction to 15% oxygen in the exhaust gases (ppmv @ 1.5% O2). In the time before the harmful effects of NOX were known, NOX emissions from the gas turbine exhaust were very high.
    By improving the construction of the combustion chamber, NOX was successfully reduced to typically a few hundred ppmv @ 15% O2. That was what the gas turbine industry could achieve in a first step.
    By redesigning the burner so that injection of water or steam became possible, NOX could be reduced to 25ppmv @ l 5% O2, which has long been standard and is still standard in some contexts. Through solid work by the gas turbine manufacturers, the latest step now results in guaranteeing 9 ppmv @ 15% O2 on certain machines.
    It is the authorities that set the limit for permitted emissions. For gas turbine operators, it is necessary to meet the regulatory requirements to obtain an operating license. The authorities formulate their requirements according to what the gas turbine industry can achieve. There is a concern among gas turbine operators for new and lower NOX requirements in the future as new requirements can result in expensive investments in new equipment and in the western case there may be talk of three stops. It is an object of this invention to satisfy the gas turbine users in that the NOX reduction according to the invention can be applied to existing gas turbine installations.
    To achieve low NOX emissions, there are three ways to go. The first way is to design the combustion chamber so that the flame temperature is kept low. Different gas turbine manufacturers have different solutions where a common principle is to divide the combustion into several stages so that an understochiometric combustion takes place first, so-called "lean combustion", followed by a second final combustion.
    The temperature lowering effect is noticeable with this method. The other way to go is to cool the flame by injecting into the combustion chamber a cooling medium such as water or steam.
    Water is particularly effective as the steam generating heat required to boil the water has a powerful effect on lowering the fl breast temperature. The third way to go is to dilute the fuel with an inert that absorbs the heat through its heat capacity. In the latter case, injection of nitrogen or carbon dioxide is common.
    The parameter that is most important to control in NOX control is, as previously stated, the temperature. The flame temperature is highest during stoichiometric combustion.
    During overstoichiometric combustion, the fl am temperature drops as the excess air acts to cool the fl am. In subchiometric combustion, not all fuel is burned and the excess fuel helps to keep the fl am temperature low. From this it appears that a method of burning the fuel is to first burn a part in a sub-stoichiometric combustion, so-called "lean combustion" in a second step to supply additional oxygen for the final combustion. This is the basis for the gas turbine manufacturers' latest constructions of so-called "dry low NOX bumers" where dry means that injection of water or steam is not necessary.
    In summary, it can be said that the latest gas turbine models are equipped with a low NOX burner that can handle at least 25 ppmv @ 15% O2 and in many cases 9 ppmv @ 15% O2 without steam or water injection. For the older gas turbine models, the manufacturers offer replacement burners with lower emissions, but that water or steam injection may still be relevant in cases with stringent emission requirements.
    In this context, it should be mentioned that the gas turbine exhaust gases contain pollutants other than NOX. This includes carbon monoxide emissions resulting from incomplete combustion of the fuel's carbon, sulfur dioxide and sulfur trioxide resulting from sulfur in the fuel, unburned hydrocarbons (UHC) resulting from incomplete combustion of intermediates in the fuel combustion, and particles and fumes.
    These pollutants are not related to the invention.
    What has been said above about emissions and pollutants primarily applies to the natural gas-fired gas turbine. Natural gas is completely dominant as a fuel for stationary gas turbines. What has been said above about NOX formation generally also applies to oil-fired gas turbines, although NOX formation is generally higher when operating with fl liquid fuels. An interesting gas turbine fuel is synthesis gas.
    Synthesis gas can be produced by reforming natural gas or by e.g. gasification (partial oxidation) of carbonaceous raw materials such as coal, oil or biomass. Especially gasification of biomass 3 is of great interest in that its carbon dioxide emissions are considered to be climate neutral as the plants absorb the emitted carbon dioxide in a closed cycle.
    The composition of the synthesis gas varies greatly depending on the production method. The combustible components are hydrogen, carbon monoxide and methane. Non-combustible components are carbon dioxide, water vapor and nitrogen. Most other components can also be included, but then in smaller quantities. A significant difference between synthesis gas and natural gas is the much lower calorific value, about one-fifth to one-tenth of the conservation value in natural gas. The lower calorific value of the synthesis gas can create difficulties in the operation of the gas turbine, in some cases so great difficulties that not all gas turbine manufacturers offer operation on synthesis gas.
    When it comes to synthesis gas and NOX formation, the situation is unfortunate. The most important combustible components of synthesis gas are hydrogen and carbon monoxide. Hydrogen combustion is characterized by a very high fl am temperature but a very fast combustion process. High temperature results in NOX. On the other hand, carbon monoxide combustion is characterized by a lower fl am temperature but a slow combustion process. Slow combustion dryness results in NOX. When hydrogen and carbon monoxide are burned together, the worst of the situations arises, namely a high fl am temperature and a slow dry burning process, whereby NOX formation becomes extensive.
    NOX values for various fuel components are reported from a laboratory measurement made by a gas turbine manufacturer. The measurements are reported in the document Gas Turbine Emissions and Control, published by General Electric Power Systems. The middle column in the table Table 2 reports NOX values for different fuel components relative to methane. Methane has been chosen as a reference as methane is representative of natural gas. The measurements are made with the same combustion chamber and at the same fuel temperature and air temperatures and otherwise equivalent conditions.
    The table values show 3,966-4,029ppmv H2 / ppmv CH4 and 1835-3928 ppmv CO / ppmv CH4, respectively. Thus, the table values say that hydrogen and carbon monoxide each generate significantly more NOX than methane.
    Another factor to consider when operating with synthesis gas is the lower calorific value. Low protection value means that a larger amount of fuel must be supplied to the combustion chamber to achieve the same protection effect.
    Here a purely practical problem arises in making combustion chamber components, such as pipes and nozzles, large enough to handle the larger volume fl of the synthesis gas. The larger nozzle simply does not fit in the combustion chamber. It is not uncommon among operational 4 synthesis gas fed gas turbines that the gas turbine must operate at reduced power as the burner system cannot receive a higher gas fl fate.
    In summary, the invention has two purposes. A first purpose is to reduce damage to the environment through reduced NOX formation. A second object is to reduce the volume of the synthesis gas in order to remove operational obstacles in the gas turbine's fuel system. The invention is practiced without modifying the gas turbine.
    Summary of the invention The invention relates to a device for conditioning fuel to a gas turbine engine, wherein the fuel comprises at least carbon monoxide and hydrogen. The fuel from an inlet passes through a reactor 11a-b and the gas turbine engine is supplied with conditioned fuel from the reactor 11a-b. Reactor 11a-b comprises a catalyst 12 which combines at least part of the carbon monoxide and hydrogen into alcohols, which advantageously gives a lower NOX during combustion.
    In a particularly advantageous embodiment of the invention, at least part of the fuel passes, before it reaches reactor 11a-b, one passage of a heat exchanger 10 which raises the temperature of the fuel and where the conditioned fuel from the reactor passes the second passage of the heat exchanger 10 before being supplied to the gas turbine engine. This advantageously increases the efficiency of the catalyst.
    In a further advantageous embodiment, the reactor 11a comprises cooling channels 27 which enable the temperature in the reactor to be controlled. In a variant at least part of the fuel is supplied to the cooling channels and after passage of the cooling channels it is supplied to the part of the fuel which has passed the reactor catalyst Catalyst 12. In a second variant water or water vapor is supplied to the cooling channels and after passage of the cooling channels the second passage of the heat exchanger. The amount fl uid passing through the cooling channels 27 can be controlled with input signals from a temperature sensor in the reactor 11a-b, so that the temperature in the reactor is optimized.
    The invention furthermore relates to such a method for conditioning fuel for a gas turbine engine.

    Brief Description of the Invention Synthetic gas has different compositions depending on how it is prepared. The invention assumes that the synthesis gas contains certain specific components. The synthesis gas must contain the combustible components hydrogen and carbon monoxide. The synthesis gas may also contain other combustible components such as methane or other hydrocarbons and sulfur compounds such as hydrogen sulfide and carbonyl sulphide. Non-combustible components can be carbon dioxide, nitrogen, water vapor and other inert gases. As a high friend value is sought, the content of combustible components must be high. For example. when gasifying biomass in a pressurized Carburettor with oxygen as the oxidation medium, the hydrogen gas and the carbon monoxide together can make up more than 60 percent of the gas volume. Furthermore, in the synthesis gas, the volume, i.e. volume per mass, is high which is caused by the low density of the hydrogen gas.
    The invention solves the problem of high NOX formation and high volume by conditioning the synthesis gas before combustion in the gas turbine. By conditioning is meant that the synthesis gas acquires better properties to perform its service as a fuel in the gas turbine after the conditioning has been carried out. Air conditioning is practiced in an air conditioning system.
    The conditioning system consists of the equipment for conditioning, which includes a catalyst equipped with a catalyst and associated peripheral equipment such as heat exchangers, pipes, valves, controllers and other equipment.
    The conditioning is done in such a way that the synthesis gas is fed to a reactor. The reactor contains a catalyst. A catalyst is a substrate that affects a propensity for a particular chemical reaction by providing support for a particular molecule formation but which in itself remains unchanged through the reaction process. The catalyst in this case has the function of reacting hydrogen (H2) and carbon monoxide (CO) to methanol (CHgOH) according to the formula 2H2 + CO -> CHgOH Methanol is a molecule composed of three parent molecules, two hydrogen molecules and a carbon monoxide molecule. The volume of the methanol molecule formed is therefore considerably smaller for the hydrogen gas and the carbon monoxide separately. The reaction thus reduces the volume of the synthesis gas. All hydrogen and carbon monoxide do not react with methanol, the conditioned synthesis gas having a composition consisting of hydrogen, carbon monoxide, methanol, and other combustible and non-combustible components that accompanied the gas from the synthesis gas source. The conditioned synthesis gas is fed to the combustion gas turbine in the combustion chamber. When the methanol is burned in the combustion chamber, reactions take place in two steps. First, methanol is decomposed according to the formula CH3OH -> CO + 2H2 This reaction is strongly endothermic so heat is needed. The heat is taken from the surrounding flame, whereby the flame temperature is lowered. In a second reaction step, the hydrogen and carbon monoxide formed react with the oxygen of the air according to the formulas "1" O 2 -> 2 CO 2 2H 2 "1" O 2 -> 2 H 2 O. These two reactions are both exothermic, giving off friend. But overall, the methanol combustion results in a low flame temperature, which is favorable from a NOX formation point of view.
    Furthermore, the decomposition of methanol is noticeable when the combustion takes place under pressurized conditions as takes place in the combustion chamber of the gas turbine. Modema gas turbines in stationary operation operate with a pressure ratio typically between 1:10 and 1:30.
    That methanol is favorable for low NOX formation in a gas turbine is documented in the previously mentioned document Gas Turbine Emissions and Control where the previously mentioned table Table 2 indicates the relative NOX formation for methanol to 0.489-0.501 ppmv methanol / ppmv methane.
    The low NOX formation is explained, among other things, by the fact that the relative stoichiometric fl am temperature as stated in Table 2 is 0.417-0.617 relative to methane. Thus, fuel containing methanol will reduce the formation of NOX.
    As described above, the object of the invention is to condition synthesis gas by reacting parts of certain gas components in the synthesis gas in a catalyst-equipped reactor to form alcohols such as methanol. The surprising effect of the invention is that two problems, NOX formation and the volume of the gas, are solved simultaneously by the same measure and that the problem reduction is enhanced by the fact that there is a pressurized relationship during the exercise.
    Description of Preferred Embodiments The reactor, the catalyst and its peripheral systems can be arranged in many different embodiments, all of which serve the same purpose. The detailed description of the invention therefore gives examples of two different embodiments, but that a person skilled in the art can easily find many variants of the embodiment and which all achieve the same purpose.
    The choice of catalyst or the method of preparing the catalyst is not essential to achieve the purpose of the invention. The catalyst can be of different types composed of one or more of the substances. For the methanol reaction, it is known that nickel, copper, iron are suitable substances to start from and which are then supplemented in the manufacturing process with e.g. zinc oxide, alumina or earth metals to achieve better properties. Furthermore, the catalyst can be prepared with the property of preventing coke formation or preventing the catalyst from being poisoned by unwanted substances in the synthesis gas blocking the active surfaces of the catalyst. Catalysts can be prepared specifically to suit the purpose of the invention. However, your catalyst manufacturers also offer ready-made catalysts that can be used in the invention.
    In the brief description of the invention, methanol was stated to be the molecule formed in the reactor. However, practical catalysts may have the property of forming other alcohols as well as hydrocarbons. In the further description of the invention, the term "alcohols" refers to a case with only methanol or cases consisting of a mixture of methanol, ethanol, propanol, butanol, pentanol and which may also contain hydrocarbons such as ethylene, ethylene, propylene, propane, butylene, butane . The fact that "alcohols" contain, in addition to methanol, other alcohols and hydrocarbons is not essential to the practice of the invention.
    F ig. l shows a generalized and simplified fl diagram of the condition of the conditioning system.
    The plant consists of a heat exchanger 10 and a reactor 11a where reactor 11a contains a bed with a catalyst 12 where the catalyst bed is in the form of a container filled with a catalyst in the form of pellets or granules and designed so that gas can flow through the catalyst bed. Synthesis gas is generated from a synthesis gas source 1 and passed in a line 13 to heat exchanger 10. The gas is preheated in heat exchanger 10. After preheating, the synthesis gas is passed in a line 14 to reactor 11a where part of the hydrogen gas and part of the carbon monoxide react to alcohols.
    The reactions benefit from the preheating of the gas. The reactions are exothermic with the temperature of the outgoing gas in line 15 being higher than the incoming gas in line 14. In heat exchangers 10 a part of the heat of reaction is transferred to the incoming gas in line 13.
    The now conditioned gas in line 16a is fed to the gas turbine 2.
    Example 1 Fig. 2 shows a first example of an embodiment of the conditioning system. The purpose of this embodiment is to enable powerful NOX reduction by converting a large proportion of hydrogen and carbon monoxide to methanol and adding steam to the synthesis gas. For this embodiment, a methanol catalyst with the commercial designation ICI Katalco methanol catalyst 51-8PPT has been chosen, as an example. The catalyst is built around the combination of Zn, Al, Cu and Mg oxide.
    In fi g.2, primary gas is fed from a synthesis gas source in line 13 to heat exchanger 10 and further in line 14 to reactor 11b. The pressure in the reactor is selected to 30 bar as being a suitable pressure for a gas turbine operating at a pressure ratio of 1:20. In the reactor, the gas passes through catalyst bed 12, whereby hydrogen gas and carbon monoxide react and form alcohols where the alcohols are in the form of steam. As the reaction is strongly exothermic, the catalyst bed must be cooled to avoid overheating. The catalyst bed is cooled by cooling ducts 27 in the form of multiple boiler tubes through the catalyst bed. Cooling water 29 is supplied to the inlet of the cooling ducts. The pressure of the cooling water is chosen so that the water boils in the cooling channels according to the saturation temperature of the water 25 ° C where 250 ° C is a suitable bed temperature for this catalyst. The steam leaves the cooling channels in line 28. By boiling the water at a certain temperature, a good temperature control is obtained in the catalyst bed. After the reactor, the gas is fed in line 15 to the heat exchanger. In the heat exchanger, the gas emits heat to the primary gas, which is thus preheated before entering the reactor. The cooled synthesis gas 26 is combined with the steam in line 28 via pressure reducing valve 202 and line 203. The now conditioned gas in line 16b is fed to the gas turbine.

Table 1 aims to compare the unconditioned primary gas with the conditioned gas to illustrate the benefits of the conditioning. Table 1 shows that the conditioning results in the volume decreasing from 0.123 m3 / kg to 0.091 m3 / kg and the fl am temperature decreasing from 2381 ° C to 2213 ° C.
    Fig. 3 shows a second example of an embodiment of the air conditioning system. This embodiment results in a minor conversion of hydrogen and carbon monoxide to alcohols. This embodiment can find application for gas turbines that need to improve their margins against undue NOX emissions. Characteristic of plant 301 is that the heat development in the reactor is smaller due to the smaller conversion of hydrogen gas and carbon monoxide and that the reactor can be cooled without the supply of extreme medium. Thus, all energy is conserved in such a way that the chemical energy released by the exothermic reactions is converted into thermal energy in the form of an increase in the temperature of the gas. The thermal energy is utilized in the expansion of the turbine. For this example, an ADM (alkali doped molybdenum sulfide catalyst) type catalyst has been selected which is characterized by good reactivity at a lower pressure than the pressure selected in the previous example.
    With this catalyst, a variety of reactions take place which form methanol and other alcohols as well as hydrocarbons.
    In Fig. 3, a primary gas is fed from a synthesis gas source in line 13. The pressure in the reactor in this example is selected to 20 bar as being a suitable pressure for a gas turbine operating at a pressure ratio of 1:15. The gas in the line is divided into a first part in line 34 to a control valve 36 and a second part in line 35 to reactor 11b via line 14. Reactor 11b contains a catalyst bed 12 where a part of the hydrogen gas and the carbon oxide react to alcohols. After the catalyst bed, the gas leaves the reactor in line 42. If the reactions lead to too high temperatures in the reactor, the catalyst bed can be cooled. This is done by gas in line 34 passing control valve 36 and further in line 37 to cooling ducts 27 in the reactor. The gas in the cooling ducts is heated by the heat of reaction in the catalyst bed and leaves the cooling ducts in line 40. The gas in line 40 is combined with the gas in line 42. The mixed gas in line 15 is fed to heat exchanger 10 where the gas gives off heat to the primary gas. After cooling, the now conditioned gas in line 16b is fed to the gas turbine. The temperature control takes place through a temperature sensor (not shown for the sake of clarity) in the reactor where the output signal of the temperature sensors is connected to a controller (not shown for the sake of clarity) which regulates control valve 36. 11 Table 2 Primary gas H2 vol% 42.0% CO vol% 42.4% C02 vol % 4.0% H20 vol% 0.2% CH4 vol% 93% Other components vol% 2.0% Alcohols vol% 0.0% Volume m3 / kg 0.087 Flame temperature ° C 2238 Conditioned gas H2 vol% 27.5% CO vol% 29.3% C02 vol% 153% H20 vol% 0.1% CH4 vol% 13.9% Other components vol% 2.7% Alcohols vol% ll.1% Volume m3 / kg 0.062 12 Flame temperature ° C 21 88 Table 2 shows estimated performance of conditioning system 301.
