专利摘要:
Das erfindungsgemäße NaA-Zeolithgranulat ist durch die folgende Parameter gekennzeichnet: Adsorptionsdaten: (p/po = 0,8, 20°C) Hergestellt wird das Zeolithgranulat, indem man pulverförmigen Zeolith A in einem Mischer vorlegt, Alkalisilikatlösung hinzugibt, solange mischt, bis man ein Zeolithgranulat mit einer Korngröße von wenigstens 0,1 mm erhält, dieses Granulat gegebenenfalls nachrollt, das feuchte Zeolithgranulat in einem Fließbetttrockner zunächst bei Temperaturen von 20 bis 39°C trocknet, wobei man den Kohlendioxidgehalt der Trockenluft auf weniger als 200 ppm einstellt, anschließend in einem zweiten Trockenschritt bei Temperaturen von 40 - 120°C und gegebenenfalls in einer dritten Trockenstufe bei 121 und 200°C unter sonst gleichen Bedingungen trocknet und anschließend das so erhaltene Granulat bei Temperaturen von höchstens 600°C in einem Drehrohr aktiviert. Das Zeolithgranulat wird bei der Herstellung von Isolierglasfenster verwendet.

This invention relates to methods for producing granular zeolites that can be used in the preparation of insulating pane.
The aim of the invention is to increase the selectivity to water vapor, due to the production of a zeolite having adsorption rates,%: (p / p 0.8;): 22.0; , 0; CO t 0,1; 02 0.1; NZ bo, 1; Ar i 0,1;

P p -I me R 1. 100 kg of zeolite A are placed in a screw mixer. 30 kg of water glass are added to it through a nozzle by spraying (module 3.38; 4.8 wt.%; SiO 15.7 May.%. Granules with a particle size of 0.1 are obtained. -3 mm, which are then additionally molded in a disk granulator. Thus, a narrow range of particle size dispersion (0.3-2.5 mm) is obtained. The granulation is sieved, in the wet state, into 1–2 mm granulometric fractions. mm, 2 mm. The particle size fraction of 1-2 mm is dried in a fluid bed dryer at 35 ° C in the first stage and 110 ° C in the second stage. their gases are allowed to circulate so that the CO content in the air is 150 h / min. The partial pressure of water vapor is 21 mm Hg in the first stage, 117 mm Hg in the second stage. The granulate is activated at 420 With in a rotating drum.
