METHOD FOR MANUFACTURE CATALYST MATERIAL FROM DESULFURIZATION WASTE CATALYST OF AN OIL REFINERY

摘要

The present invention relates to a process for the purification of crude oil, which comprises using a waste catalyst dissolved in an alkali or acid, diluting it with water, making an acidic solution, adding monooxylamine to the vanadium first, adding soda ash or methyl acetate, , And methyl ethanol to solidify the metal components, precipitate the precipitates, wash them with water, and oxidize them by a heating method. Thus, a metal oxide mixed with nickel oxide, cobalt oxide, molybdenum oxide and aluminum oxide can be obtained and used as a catalyst material .;Spent catalyst, vanadium, mono-oxyamine, spent catalyst
