ABSTRACT:
A process for catalytic hydrodewaxing hydrocarbon feedstocks is disclosed. The catalyst comprises a surface-modified crystalline aluminosilicate zeolite, such as ZSM-5 type zeolite in a matrix or binder, such as alumina, having a specified metals content. The process is especially useful for dewaxing lubricating oil basestocks.
