Abstract: Disclosed is a synthetic zeolite by means of which gas streams containing steam and carbon dioxide as impurities can be purified. The zeolitic adsorbing agent is a 13X type or LSX type faujasite or a mixture of both types that are deformed with a binder, at least some parts of which are highly dispersed. Said novel adsorption system allows extraordinarily high adsorption capacities to be obtained while keeping the mass transfer zones short resulting in a longer service life of the adsorption systems before carbon dioxide is able to break through.

Abstract: A process for the production of a molecular sieve adsorbent blend with improved performance characteristics produced by preparing a zeolite material, which may include zeolite 13X, zeolite LSX or mixtures thereof, preparing a binder which includes highly dispersed attapulgite fibers alone or blended with a non-highly dispersed attapulgite clay, mixing the zeolite material with the binder to form a mixture, forming molecular sieve adsorbent blends into a shaped material and treating the shaped material, wherein the tapped bulk density of the highly dispersed attapulgite fibers measured according to DIN/ISO 787 is more than about 550 g/ml.
