  • 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.

  • Process for a continuous synthesis of zeolitic materials
    Patent number: 11046587
    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.
