DESULFURIZING AGENT, MANUFACTURING METHOD THEREFOR, AND DESULFURIZATION METHOD FOR HYDROCARBON OIL USING THIS

摘要

PROBLEM TO BE SOLVED: To provide a desulfurizing agent capable of stably and economically desulfurizing a hydrocarbon oil under a specific condition for a long period of time. SOLUTION: The desulfurizing agent contains 1-30 mass% of nickel, 30-80 mass% of zinc and 0.1-20 mass% of one kind or more of elements selected from Group 4A, and has a specific surface area of 70 m2/g or higher after it is reduced in a hydrogen gas stream. The desulfurizing agent can be manufactured by simultaneously dropwise adding an acidic solution and an alkaline solution containing nickel, zinc and one kind or more of elements selected from Group 4A to water and producing precipitation.
