Abstract
(EN)
The present invention relates to a process for preparing a zeolitic material comprising YO2 and X2O3 in its framework structure, wherein Y stands for a tetravalent element and X stands for a trivalent element, wherein said process comprises: (i) preparing a mixture comprising one or more sources of YO2, one or more sources of X2O3, and H2O; (ii) grinding and/or mixing the mixture prepared in (i), wherein the energy intake of the mixture during the grinding and/or mixing procedure is in the range of from 0.3 to 200 kJ/kg of the mixture; (iii) adding water, preferably distilled water, to the ground mixture obtained in (ii) and preferably homogenizing the resulting mixture; and (iv)crystallizing a zeolitic material comprising YO2 and X2O3 in its framework structure from the mixture obtained in (iii), wherein the mixture is heated to a temperature in the range of from 80 to 300°C; wherein the mixture prepared in (i) and ground in (ii) contains from 5 to 300 wt.-% of H2O based on 100 wt.-% of the one or more sources of YO2, calculated as YO2. Furthermore, the invention relates to a zeolitic material comprising YO2 and X2O3 in its framework structure as obtainable and/or obtained according to the inventive process as well as to the use of said material.
