| abstract |
The present invention relates to a continuous process for preparing a zeolitic material comprising (i) preparing a mixture comprising a source of YO 2 , optionally a source of X 2 O 3 , 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. |
