ABSTRACT:
Hydrocarbon hydroprocessing using catalysts containing a Group VIB metal and a phosphorus component on a porous refractory oxide is prepared by impregnating support particles with a solution containing (1) phosphorus, and (2) citric acid in a mole ratio to Group VIB metal components of less than 1 to 1, followed by drying and calcining. The catalysts are useful for promoting a number of hydrocarbon hydroprocessing reactions, particularly those involving hydrogenative desulfurization, demetallization and most particularly, denitrogenation.
