Title (EN) DOUBLE LAYER ZEOLITES AND PREPARATION THEREOF
(FR) ZÉOLITES À DOUBLE COUCHE ET LEUR PRÉPARATION
Abstract:
(EN) Multi-layered or core/shell structured zeolites and processes of making the same are disclosed. The zeolites can include a first zeolite having a first silica (SiO2) to alumina (Al2O3) ratio (SAR) and a second zeolite that is in direct contact with the first zeolite defining an interface between the first and second zeolites, the second zeolite being a pure silica zeolite or having a second SAR ratio that is different than the first SAR ratio, wherein the silicon (Si) and optionally aluminum (Al), if present, in the second zeolite is from the first zeolite, and the first and second zeolites are different zeolites.
(FR) L'invention porte également sur des zéolites à structure multicouche ou noyau/enveloppe et sur leurs procédés de fabrication. Les zéolites peuvent comprendre une première zéolite ayant un premier rapport silice (SiO2) sur alumine (Al2O3) (SAR) et une seconde zéolite qui est en contact direct avec la première zéolite définissant une interface entre les première et seconde zéolites. La seconde zéolite est une zéolite de silice pure ou a un second rapport SAR qui est différent du premier rapport SAR. Le silicium (Si) et éventuellement de l'aluminium (Al), si présent, dans la seconde zéolite est de la première zéolite, et les première et seconde zéolites sont des zéolites différentes.
