  • Process for a continuous synthesis of zeolitic materials using seed crystals loaded with organotemplate
    Patent number: 11623868
    Abstract: Disclosed herein is a continuous process for preparing zeolitic material with a CHA-type framework structure comprising SiO2 and X2O3 and the zeolitic material so-obtained. The processes comprises (i) preparing a mixture comprising one or more sources of SiO2, one or more sources of X2O3, seed crystals, one or more tetraalkylammonium cation R5R6R7R8N+-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.
