(EN) MECHANOCHEMICAL ACTIVATION IN ZEOLITE SYNTHESIS
(FR) ACTIVATION MÉCANOCHIMIQUE DANS LA SYNTHÈSE DE ZÉOLITE
Abstract
(EN)
The present invention relates to a process for the preparation of 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 5 to 2,000 kJ/kg of the mixture; (iii) heating the mixture obtained in (ii) at a temperature in the range of from 80 to 300 °C for crystallizing a zeolitic material comprising YO2 and X2O3 in its framework structure from the mixture; wherein the mixture prepared in (i) contains from 100 to 1,500 wt.-% of H2O based on 100 wt.-% of the one or more sources of YO2, calculated as YO2, contained in the mixture prepared in (i) and heated in (iii). 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.
(FR)
L'invention concerne un procédé de préparation d'un matériau zéolithique comprenant du YO2 et du X2O3 dans sa structure d'ossature, Y désignant un élément tétravalent et X désignant un élément trivalent, ledit procédé consistant : (i) à préparer un mélange comprenant une ou plusieurs sources de YO2, une ou plusieurs sources de X2O3, et de l’H2O ; (ii) à broyer et/ou à brasser le mélange préparé à l’étape (i), l'apport d'énergie du mélange pendant l’opération de broyage et/ou de brassage étant situé dans la plage de 5 à 2 000 kJ/kg du mélange ; (iii) à chauffer le mélange obtenu à l’étape (ii) à une température située dans la plage de 80 à 300 °C afin de cristalliser un matériau zéolithique comprenant du YO2 et du X2O3 dans sa structure d'ossature à partir du mélange ; le mélange préparé à l’étape (i) contenant de 100 à 1 500 % en poids d’H2O sur la base de 100 % en poids de ladite source de YO2, calculé en tant que YO2, contenu dans le mélange préparé à l’étape (i) et chauffé à l’étape (iii). En outre, l'invention concerne un matériau zéolithique comprenant du YO2 et du X2O3 dans sa structure d'ossature pouvant être obtenue et/ou obtenue selon le procédé de l'invention ainsi que l'utilisation dudit matériau.
