Title (EN) ZEOLITES WITH HIERARCHICAL POROSITY
(FR) ZÉOLITHES À POROSITÉ HIÉRARCHISÉE
Abstract: front page image
(EN)The present invention concerns Y-type FAU zeolites with hierarchical porosity having an Si/AI atomic ratio strictly greater than 1.4 and less than or equal to 6, having controlled and optimised crystallinity, and having mesoporosity such that the mesoporous outer surface area is between 40 m2. g-1 and 400 m2. g-1. The present invention also concerns the method for preparing said Y-type FAU zeolites with hierarchical porosity.
(FR)La présente invention concerne des zéolithes FAU de type Y à porosité hiérarchisée de rapport atomique Si/AI strictement supérieur à 1,4 et inférieur ou égal à 6, de cristallinité contrôlée et optimale, et présentant une mésoporosité telle que la surface externe mésoporeuse est comprise entre 40 m2. g-1 et 400m2. g-1. La présente invention concerne également le procédé de préparation des dites zéolithes FAU de type Y à porosité hiérarchisée.
