The present invention relates to a process for the preparation of a zeolitic material, as well as to a catalyst per se as obtainable or obtained according to said process. Furthermore, the present invention relates to the use of the zeolitic material, in particular as a catalyst.

Zeolite synthesis in a reactor with controlled velocity profile

Disclosed herein is a continuous process for preparing zeolitic material with a CHA-type framework structure comprising SiOand XOand the zeolitic material so-obtained. The processes comprises (i) preparing a mixture comprising one or more sources of SiO, one or more sources of XO, seed crystals, one or more tetraalkylammonium cation RRRRN-containing compounds as structure directing agent, and a liquid solvent system; (ii) continuously feeding the mixture prepared in (i) into a continuous flow reactor at a liquid hourly space velocity; and (iii) crystallizing the zeolitic material with a CHA-type framework structure from the mixture in the continuous flow reactor.

Process for a continuous synthesis of zeolitic materials using seed crystals loaded with organotemplate

A continuous process for preparing a zeolitic material comprising (i) preparing a mixture comprising a source of YO, optionally a source of XO, and a liquid solvent system; (ii) continuously feeding the mixture prepared in (i) into a continuous flow reactor at a liquid hourly space velocity in the range of from 0.3 to 20 h1 for a duration of at least 1 h; and (iii) crystallizing the zeolitic material from the mixture in the continuous flow reactor, wherein the mixture is heated to a temperature in the range of from 100 to 300&#xb0; C.; wherein the volume of the continuous flow reactor is in the range of from 150 cmto 75 m, as well as to zeolitic materials which may be obtained according to the inventive process and to their use.
