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.
Catalyseurs de déparaffinage d'apports d'hydrocarbures notamment à forte teneur en soufre et en azote. Lesdits catalyseurs comportent un zéolite a faible rapport silice/alumine combiné à un liant à faible surface, ou en variante un zéolite à fort rapport entre sa surface spécifique et la surface spécifique extérieure.
