Hydrocarbon conversion catalysts contain at least one Group VIB metal component, at least one Group VIII metal component, and a phosphorus component on a porous refractory oxide and have a narrow pore size distribution including at least about 75 percent of the total pore volume in pores of diameter from about 70 to about 130 angstroms. The catalyst is useful for promoting a number of hydrocarbon conversion reactions, particularly those involving hydrogenative desulfurization.

Desulfurization catalyst and the catalyst prepared by a method

Deactivated hydrorefining catalysts are regenerated by incorporation of a phosphorus component followed by combustive coke-removal from the catalyst. The regenerated catalyst is useful for promoting hydrodesulfurization reactions, particularly those involving demetallation of hydrocarbons.

Hydrorefining with a regenerated catalyst

Hydrotreating with a catalyst comprising molybdenum, nickel, and phosphorus active components supported on gamma alumina is prepared with gamma alumina support particles which have been contacted with aqueous ammonia.

Hydrotreating catalyst and process

A hydrotreating catalyst comprising molybdenum, nickel, and phosphorus active components supported on gamma alumina is prepared with gamma alumina support particles which have been contacted with aqueous ammonia and is employed in the hydrotreating process to reduce the sulfer and nitrogen content of hydrocarbons.

Hydrotreating catalyst

A hydrotreating catalyst comprising nickel, molybdenum, and phosphorus active components supported on gamma alumina is prepared with gamma alumina support particles partially hydrated with water vapor while the support particles are in motion relative to each other, as by passage of steam through an ebulliating bed of particulate gamma alumina.
