摘要:
Catalysts for dewaxing of hydrocarbon feeds, particularly feeds with elevated sulfur and nitrogen levels, are provided. The dewaxing catalysts include at least two zeolites, including a zeolite with a low silica to alumina ratio. The catalysts may be combined with a low surface binder, or alternatively the catalysts as formulated may have a high ratio of zeolite surface area to external surface area.
