Abstract
(EN)
Provided is a process for the preparation of a zeolitic material comprising YO 2 and X 2O 3 in its framework structure, wherein Y stands for a tetravalent element and X stands for a trivalent element, wherein the process comprises:(i) preparing a mixture comprising one or more sources of YO 2, one or more sources of X 2O 3, and H 2O; (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) heating the mixture obtained in (ii) at a temperature in the range of from 80 to 300 ℃ for crystallizing a zeolitic material comprising YO 2 and X 2O 3 in its framework structure from the mixture; wherein the mixture prepared in (i) contains from 5 to 200 wt.% of H 2O based on 100 wt.% of the one or more sources of YO 2, calculated as YO 2, contained in the mixture prepared in (i) and heated in (iii). Furthermore, a zeolitic material comprising YO 2 and X 2O 3 in its framework structure as obtainable and/or obtained according to the process as well as the use of the material are provided.
(FR)
L'invention concerne un procédé de préparation d'un matériau zéolithique comprenant du YO 2 et du X 2O 3 dans sa structure, dans laquelle Y représente un élément tétravalent et X représente un élément trivalent, le procédé comprenant : (i) la préparation d'un mélange comprenant une ou plusieurs sources de YO 2, une ou plusieurs sources de X 2O 3, et du H 2O; (ii) le broyage et/ou le mélange du mélange préparé en (i), l'apport d'énergie du mélange pendant la procédure de broyage et/ou de mélange étant dans la plage de 0,3 à 200 kJ/kg du mélange; (iii) le chauffage du mélange obtenu dans (ii) à une température dans la plage de 80 à 300 °C pour cristalliser un matériau zéolithique comprenant du YO 2 et du X 2O 3 dans sa structure à partir du mélange; le mélange préparé en (i) contient de 5 à 200 % en poids de H 2O sur la base de 100 % en poids de des sources de YO 2, calculé en tant que YO 2, contenu dans le mélange préparé en (i) et chauffé en (iii). En outre, un matériau zéolithique comprenant du YO 2 et du X 2O 3 dans sa structure telle qu'obtenue et/ou obtenue selon le procédé ainsi que l'utilisation du matériau.
