| 摘要 |
A catalyst useful for hydroprocessing a hydrocarbon-containing oil contains at least one hydrogenation component on an amorphous, porous refractory oxide containing delta alumina. The catalyst is prepared by impregnating support particles having a narrow pore size distribution and a median pore diameter greater than about 185 angstroms with a solution containing a precursor of the hydrogenation components, followed by drying and calcining. The catalyst is useful for promoting a number of hydrocarbon hydroprocessing reactions, particularly hydrogenative desulfurization, demetallation and denitrogenation, and most particularly, hydrodemetallation of residuum-containing oils.
