Abstract
There is provided a process for demetallizing hydrocarbon feedstocks, such as resids or shale oil. The process uses a catalyst comprising at least one hydrogenation metal, such as nickel and molybdenum, and an ultra-large pore oxide material. This ultra-large pore oxide material may have uniformly large pores, e.g., having a size of about 40 Angstroms in diameter.
Claims20
A process for demetallizing a hydrocarbon feedstock, said process comprising contacting said hydrocarbon feedstock with a catalyst under sufficient demetallation conditions, said catalyst comprising at least one hydrogenation metal and an inorganic, porous crystalline phase material having, after calcination, a hexagonal arrangement of uniformly-sized pores having diameters of at least about 13 Angstrom Units and exhibiting a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom units.
A process for demetallizing a hydrocarbon feedstock, said process comprising contacting said hydrocarbon feedstock with a catalyst under sufficient demetallation conditions, said catalyst comprising at least one hydrogenation metal and an inorganic, porous non-layered crystalline phase material exhibiting, after calcination, an X-ray diffraction pattern with at least one peak at a d-spacing greater than about 18 Angstrom Units with a relative intensity of 100 and a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 50 torr and 25.degree.
