Abstract

The present invention relates to A process for the production of a molding, comprising (I) providing a zeolitic material; (II) mixing the zeolitic material provided in step (I) with one or more binders; (III) kneading of the mixture obtained in step (II); (IV) molding of the kneaded mixture obtained in step (III) to obtain one or more moldings; (V) drying of the one or more moldings obtained in step (IV); and (VI) calcining of the dried molding obtained in step (V); wherein the zeolitic material provided in step (I) displays a water adsorption ranging from 1 to 15 wt.-% when exposed to a relative humidity of 85%, as well as to a molding obtainable or obtained according to the inventive process in addition to a molding per se and to their respective use.
