Abstract
A hydrocarbon conversion catalyst suitable for converion of heavy hydrocarbon oils containing large amounts of metallic contaminants, such as petroleum residua, to lower boiling products comprises a porous inorganic oxide such as bulk alumina composited with an inorganic oxide gel matrix such as silica-alumina, and a crystalline aluminosilicate zeolite.
Claims14
A catalyst comprising:
- (1) a crystalline aluminosilicate zeolite, (2) a catalytic inorganic oxide gel, and (3) a porous inorganic oxide initially having a surface area greater than about 200 square meters per gram and having at least 0.2 cubic centimeter per gram of its pore volume in pores ranging in diameter from about 90 to about 200 angstroms, said catalyst having at least 0.4 cubic centimeter per gram of its pore volume in pores greater than 90 angstroms in diameter.
