FIELD: chemistry.

SUBSTANCE: present invention relates to a method for the production of a molding. A method for the production of a molding to use in catalytic processes is described, 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 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 absorption ranging from 3 to 10% when exposed to a relative humidity of 85 %, wherein the zeolitic material comprises one or more zeolites having a framework structure selected from the group consisting of AEI, BEA, CHA, CDO, DDR, EMT, ERI, EUO, FAU, FER, HEU, LEV, MAZ, MEI, MEL, MFI, MFS, MOR, MOZ, MRE, MTN, MTT, MTW, MWW, NON, OFF, RRO, TON, and the combinations of two or more thereof, in which the mixture obtained in step (II) is characterized by a weight ratio of one or more binders to the zeolite material (binder: zeolitic material) in the range of 0.1 to 0.6, wherein step (II) further comprises mixing the zeolitic material and one or more binders with a solvent system, the solvent system comprising one or more solvents in which the mixture obtained in step (II) has a mass ratio of the solvent system to the zeolitic material (solvent system: zeolite material) ranging from 0.7 to 1.7, wherein step (II) further comprises mixing the zeolitic material and one or more binders with one or more pore-forming agents, the method further comprising (VII) hydrothermally treating the calcined molding obtained in step (VI), the hydrothermal treatment being carried out with a water-containing solvent system and/or an aqueous solution.

EFFECT: improving the catalytic properties of zeolite materials.
