Patent ID: 7820037

Claim:
A hydrocarbon desulfurization method, said method comprising: desulfurizing a hydrocarbon raw material comprising methane, ethane, propane and butane, in the presence of hydrogen using a sulfur-adsorption type desulfurizing agent manufactured by a method comprising: mixing a mixture containing a copper compound, a zinc compound and an aluminum compound with an aqueous solution of an alkali substance to prepare a precipitate, calcining the resultant precipitate, forming the calcined precipitate into a shaped form of a copper oxide-zinc oxide-aluminum oxide mixture, impregnating the shaped form with iron and/or nickel, calcining the impregnated form to produce a calcined oxide, and reducing the calcined oxide with hydrogen to form the sulfur-adsorption type desulfurizing agent, wherein the desulfurization is performed at a space velocity (GHSV) of 200 to 10,000 h −1 .
