Abstract
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.
Claims17
A supported catalyst comprising:
- a zeolite having unidimensional 10-member ring pores and a SiO2:Al2O3 ratio of 100 or less;
- 0.1 to 5 wt.% of a metal hydrogenation component;
- and
- a metal oxide binder, wherein the metal oxide binder in powder form has a surface area of 80 m2/g or less;
- wherein the supported catalyst has a ratio of zeolite surface area to external surface area of at least 80:100.
