HYDROTREATING CATALYST

摘要

Hydrotreating catalyst composition comprising a hydrogenating component consisting essentially of a metal component in which the metal is selected from Group VIB and phosphorus component, deposed on the surface of a support comprising a porous refractory inorganic oxide and free of a zeolite component exhibits excellent hydrotreating activity and lifetime, particularly in the hydrodenitrogenation of high nitrogen feeds, e. g., whole shale oils or fractions thereof, and in the hydrodesulfurization and hydrodemetallation of high sulfur feeds, e. g., vacuum or atmospheric residua.
