A method resid hydrodesulfurization

The present invention relates to a process for hydrodesulfurizing residuum; preparation of the catalyst is aqueous ammonia was added dropwise a solution of terephthalic acid prepared by adding a nickel salt or cobalt salt, urea, and ammonium salts to obtain steep liquor, a molar ratio of 2: 1: 2.5 -5: 1-5; the volume of impregnating solution or the like impregnated into the support surface, allowed to stand at room temperature, crystallized, washed, and dried to give 80 ℃ -120 ℃ nickel salt or cobalt salt talc; formulated acid sodium salt solution of group VIII, a concentration of 14mol / L, nickel salt or cobalt salt and then immersed in a salt solution talc VIII of the acid, the pH adjusted to 4.5, the solids obtained were washed, dried at 80-100 deg.] C, at 300-700 calcination, a catalyst, the catalyst used in the present process, highly dispersed supported metal at a temperature ℃, high catalytic activity for hydrodesulfurization residual oil, up to 97-100% desulfurization rate.
