A desulfurizing agent is produced by mixing a copper compound, a zinc compound and an ammonium compound with an aqueous solution of an alkali substance to prepare or precipitate followed by calcitrating the resulting precipitate to form a calcined precipitate into a shape form of a copper oxide-zinc oxide-aluminum oxide mixture. The shaped form is impregnated with iron or nickel and calcined to produce a calcined oxide and reduced with hydrogen to form a sulfur-absorption desulfurizing agent.
