Abstract: Disclosed is a system for processing a combustible gas, which comprises a catalytic combusting means for receiving an oxygen-containing combustible gas that contains oxygen in addition to the combustible gas as the principal component thereof, causing this oxygen-containing combustible gas to contact an oxidation catalyst for partial combustion thereof, to produce the resultant partially combusted gas as a compressible combustible gas.

Abstract: 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.

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.

Abstract: In a fuel cell power generation system for use with a fuel gas which is prepared by desulfurizing a raw fuel material such as naphtha, LPG, town gas, or the like and then, processing it by steam reforming reaction and thus, consists mainly of hydrogen or a process of producing the fuel gas, the desulfurization of the raw fuel material is implemented using a copper/zinc desulfurizing agent. As a result of the desulfurization, the raw fuel material is desulfurized at a higher level and the deterioration of a steam reforming catalyst employed is prevented. Accordingly, steady long-run operation of the fuel cell will be ensured. Also, upon the steam reforming reaction, the S/C (the mole number of steam per one mole of carbon in a raw fuel material) is reduced and thus, the concentration of hydrogen in the fuel gas will be increased providing an improvement in the efficiency of power generation.

Abstract: A novel process for desulfurizing and steam reforming sulfur-containing hydrocarbons is disclosed. The process comprises the steps of (a) desulfurizing the sulfur-containing hydrocarbon to a sulfur content of 5 ppb or less by use of a desulfurization agent, (b) reforming the desulfurized hydrocarbon at low temperature in an adiabatic reactor by use of steam, and (c) reforming the resultant gas reformed in the course of step (b) at high temperature in an external-heating reformer furnance.
