CA 2710510
Catalysts for dewaxing of hydrocarbon feeds, particularly feeds with elevated sulfur and nitrogen levels, are provided. The dewaxing catalysts include a zeolite with a low silica to alumina ratio combined with a low surface binder, or alternatively the formulated catalyst has a high ratio of zeolite surface area to external surface area.
L'invention porte sur des catalyseurs pour un déparaffinage de charges d'alimentation d'hydrocarbures, en particulier de charges d'alimentation ayant des teneurs élevées en soufre et en azote. Les catalyseurs de déparaffinage comprennent une zéolite avec un rapport de silice à alumine faible, combinée à un liant d'aire de surface faible, ou en variante le catalyseur formulé a un rapport élevé d'aire de surface de zéolite à aire de surface externe.
