Abstract
A method for the desulfurization of hydrocarbons by desulfurizing unsaturated hydrocarbons or hydrocarbon materials containing unsaturated hydrocarbons, in the presence or absence of hydrogen, using a copper-zinc desulfurizing agent prepared by the co-precipitation method. By this method, the sulfur content of the hydrocarbons can be reduced while suppressing hydrogenation of the unsaturated hydrocarbons.
