PROCESS FOR THE ORGANOTEMPLATE-FREE SYNTHETIC PRODUCTION OF A ZEOLITIC MATERIAL USING RECYCLED MOTHER LIQUOR |
摘要 |
<p>The present invention relates to an organotemplate-free synthetic process for the production of a zeolitic material comprising YO2 and X2O3, wherein said process comprises the steps of (1) preparing a mixture comprising seed crystals, one or more sources for YO2, one or more sources for X2O3, and one or more solvents; (2) crystallizing the mixture obtained in step (1) to obtain a zeolitic material comprising YO2 and X2O3 as a crystallization product; wherein Y is a tetravalent element, and X is a trivalent element, and wherein at least a portion of the mother liquor obtained in step (2) is recycled to step (1) as a source for YO2, optionally after concentration of the mother liquor.</p> |
