NOBLE METAL HYDROGENATION CATALYSTS WITH LOW CRACKING ACTIVITY

Methods are provided for modifying hydrogenation catalysts having silica supports (or other non-alumina supports) with additional alumina, and using such catalysts to achieve unexpectedly superior hydrogenation of feedstocks. The modified hydrogenation catalysts can have a relatively low cracking ac...

Beschreibung
Zusammenfassung:	Methods are provided for modifying hydrogenation catalysts having silica supports (or other non-alumina supports) with additional alumina, and using such catalysts to achieve unexpectedly superior hydrogenation of feedstocks. The modified hydrogenation catalysts can have a relatively low cracking activity while providing an increased activity for hydrogenation. L'invention concerne des procédés permettant de modifier des catalyseurs d'hydrogénation ayant des supports en silice (ou d'autres supports sans alumine) avec de l'alumine supplémentaire, et d'utiliser de tels catalyseurs pour réaliser de manière inattendue une meilleure hydrogénation de supérieure de matières premières. Les catalyseurs d'hydrogénation modifiés peuvent avoir une activité de craquage relativement faible tout en assurant une activité accrue pour l'hydrogénation.
