摘要:
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.

摘要:
A catalytic composition comprises a metal hydrogenation- dehydrogenation component supported on a support material comprising an ultra-large pore crystalline material of high surface area and porosity. The crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., and has uniformly sized pores with a maximum perpendicular cross section of at least about 13 .ANG.. In a preferred form, the support material, which is preferably a metallosilicate such as an aluminosilicate, has the pores in a hexagonal arrangement, giving rise to a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG..
