摘要： A process for hydrodewaxing a hydrocarbon feedstock boiling above about 350.degree. F. by contacting the feedstock and hydrogen at a hydrogen pressure of from about 300 to about 2000 psig at a temperature of 400.degree. to 900.degree. F. and at a space velocity of about 0.1 to about 10.0 LHSV with a catalyst comprising about 0.1 to about 23 wt. % of an oxide of a Group VIII metal, such as nickel, or an oxide of a Group VIB metal, such as molybdenum; supported on a porous alumina support containing about 50 to about 85 wt. % of a crystalline alumino-silicate zeolite of the ZSM-5 type based on the weight of the support. The catalyst is further characterized by having greater than 60% of the pore volume between 45-600 Angstroms in the 70-200 Angstrom range. The process is especially useful for dewaxing lubricating oil basestocks.
