摘要
The invention relates to a method for producing a microporous material for molecular-sieve gas separation of small molecules at high temperatures and in the presence of water. The invention addresses the problem of eliminating the disadvantages of the prior art so that the separation of hydrogen from anhydrous gas mixtures by absorption or membrane separation with porous materials at temperatures up to 800°C, as well as the separation of hydrogen and water at temperatures up to at least 300°C, is possible on a large industrial scale. This problem is solved according to the invention by a method for producing a thermally and hydrothermally particularly stable microporous aluminosilicate (zeolite), which is capable, due to the pores having a diameter of 0.3 nm in its crystalline structure, of separating small gas molecules such as hydrogen, helium and water selectively from gas mixtures by pore absorption or adsorption and permeation at elevated temperatures and in the presence of water.
