摘要：
There is disclosed an improved dewaxing process which will operate for longer periods of time involving contacting a feedstock having a 50 volume percent boiling point greater than 900.degree. F. with a crystalline aluminosilicate zeolite having a Constraint Index of from 1 to 12 and a silica-to-alumina ratio of at least 12. The crystalline aluminosilicate zeolite is composited with an inorganic oxide, such as alumina. The composite also containing a hydrogenation metal and the catalyst composite has a maximum diffusion distance of less than 0.025 inch.
