    专利说明:

    This invention relates to methods for removing sulfur, present in the form of carbon dioxide, from liquid hydrocarbons, in particular from a hydrocarbon mixture containing propylene.
    The purpose of the invention is to increase the degree of purification of the liquid hydrocarbon mixture from carbon dioxide.
    Example 1. Pass the liquid hydrocarbon mixture containing. 99% by weight of propylene and 1% by weight of propane and having a residual COS content of 2.7 ppm through an adsorbing material formed of 43.3% by weight of silicon dioxide, taken as a substrate, on which nickel is deposited, having the form NiO in the amount of 34 wt.% And having the appearance of metallic nickel in the amount of 22.7 wt.% (Nickel content 56.7 wt.%, Metallic nickel content 40 wt.% Of the total nickel).
    Before recovery, the adsorbent material contains about 49 wt.% Nickel.
    The adsorbent material is finely sprayed to an average particle size of i 1 mm, and the specific surface area of this material is 145.
    The mixture is passed through an adsorbing material at an ambient temperature of 20 ° C and at a pressure of 14 bar sufficient to maintain the mixture in a liquid state and at a volume velocity of 5.
    PRI mme R 2. Pass the liquid hydrocarbon mixture as in Example 15 but having different residual COS contents through the adsorbent material described in Example 1.
    This material is finely ground to an average particle size of 1 mm, and the specific surface of this material is H5 m2 / g.
    This mixture is passed through an adsorbing material containing nickel in accordance with the conditions given in table. 1. Pressure 14 bar.
    As shown by the results presented in Table. 1, the purified mixture contains COS in an amount less than 30 ppb (parts per billion), even when the mixture contains water, which is particularly harmful.
    PRI m e-p 3. Pass the mixture from liquid hydrocarbons, wt.%: Propylene 95.6; propane 3.8; .b in which water content is below 10 ppm.

    having a different residual COS content through the adsorbing material, similar to that specified in examples 1 and 2, except for particles, which in this case have an average size of 3.2 mm. This example illustrates the activity of the adsorbent operating for a long period of time.
    The mixture is passed at a pressure of 14 bar through a layer of adsorbing material containing nickel.
    The conditions of the method and the results are shown in Table. 2
    After 88 days of operation, the activity of the adsorbent is kept very high.
    PRI me R 4. Pass the hydrocarbon liquid mixture containing 77.4 wt.% Propylene and 22.6 wt.% Propane, with a residual content of COS. 48 ppm, through the adsorbing material containing 43.3 wt.% SiO. as a carrier on which nickel is deposited 56.7% by weight, incl. in the form of NiO oxide in the amount of 34 May. 2 and in the form of metal, lytic nickel in the amount of 22.7 wt.% (40 wt.% of metallic nickel from total nickel).
    The adsorbent material is finely ground to obtain a portion of an average value of 1 mm, the specific surface of this material 145.
    Thus, the mixture is passed through the adsorbent material at 34 ° C, OC 15 bar pressure sufficient to maintain the mixture in the liquid phase and at hourly volumetric feed rate of the mixture 5.
    A sample of the purified mixture is taken and the COS content is determined. It is 28 ppb.
    Example 5. Pass the liquid hydrocarbon mixture containing 95.4 wt.% Propylene and 4.6 wt.% Propane with a residual COS content of 1.2 ppm, through an adsorbing material, similar to example 4, at 40 ° C, a pressure of 15 bar, sufficient to maintain the mixture in the liquid phase, and at a volumetric feed rate of the charge of 0.6 h-h
    The COS content in the purified blend is 5 ppb.
    PRI me R 6. Pass the liquid g hydrocarbon mixture containing
    99% by weight of propylene and 1% by weight of propane, and with a residual COS content of 2.7 ppm, through an adsorbent matrix of 1-triple formed of 31.1% by weight,% of oxide
    silicon as a carrier, on which nickel is deposited in the amount of 68.9 wt.%, incl. in the form of NiO in the amount of 35.8 wt.%, and in the form of metallic Ni in the amount of 33.1 wt.% (48.0 wt.% of metallic nickel from total nickel).
    The adsorbent material is finely ground to obtain particles of an average size of about 1 mm, the specific gravity on the surface of this material is 154.
    Thus, the mixture is passed. through an adsorbing material at 23 ° C, a pressure of 15 bar, feeds the mixture to maintain the mixture in the liquid phase, and at a volumetric flow rate of the charge 5 h-h
    A sample of the purified mixture is sampled and the COS content is determined, which is 20 ppb.
    The process is carried out for 120 days, after which the COS content in the purified mixture is 22 ppb.
    Examples 7-10. The characteristic-.25 and the process is carried out at the temperature of the broom, the cleaning conditions and the resultant 1-40 ° C with the flow rate of the feed are shown in Table. 3, in which the mixture is 0.1–20 hours at a pressure, the values from the baseline to maintain the mixture in measures 4–6 are also given by the liquid.
