Abstract

A continuous process for preparing a zeolitic material comprising (i) preparing a mixture comprising a source of YO2, optionally a source of X2O3, 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 h−1 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° C.; wherein the volume of the continuous flow reactor is in the range of from 150 cm3 to 75 m3, as well as to zeolitic materials which may be obtained according to the inventive process and to their use.
