摘要

A desulfurizing agent for a hydrocarbon comprises: 10 to 30 percent by mass of a porous inorganic oxide based on the total mass of the desulfurizing agent; 3 to 40 percent by mass of zinc oxide; and 45 to 75 percent by mass of a nickel atom in terms of nickel oxide, wherein the reduction degree of the nickel atom is 50 to 80 percent, and wherein the amount of hydrogen adsorption per unit desulfurizing agent mass is 3.5 to 4.6 ml/g.
