[origin: EP0168146A1] A dewaxing process is disclosed which will operate for longer periods of time involving contacting a feedstock having a 50 volume percent boiling point greater than 482 DEG C (900 DEG F) with a catalyst composite of a crystalline aluminosilicate zeolite, having a Constraint Index of from 1 to 12 and a silica-to-alumina ratio of at least 12 and an inorganic oxide binder such as alumina. The catalyst composite has a maximum diffusion distance of less than 0.6 mm (0.025 inch).
