Abstract: PURPOSE: A process for producing a zeolite catalyst containing zeolite and oligomeric silica which can be used in industrial reactors is provided. CONSTITUTION: The process for the preparation of zeolitic catalysts based on the rapid drying of an aqueous dispersion comprising crystalline zeolite, oligomeric silica and tetra-alkylammonium hydroxide, is characterized in that the aqueous dispersion is prepared by directly mixing the suspension resulting from the synthesis of the zeolite with an oligomeric silica sol obtained from the hydrolysis of a tetra-alkyl ortho silicate in the presence of tetra-alkylammonium hydroxide.

Abstract: The present invention relates to a process for the preparation of zeolitic catalysts comprising zeolite and oligomeric silica, which can be used in industrial reactors. The process consists in directly mixing the suspension, resulting from the synthesis of the zeolite, with an oligomeric silica sol, obtained from the hydrolysis of a tetra-alkyl ortho silicate in the presence of tetraalkylammonium hydroxide, and in subjecting the mixture to rapid drying, by feeding to a spray-dry.
