DESULFURIZING AGENT AND METHOD FOR PRODUCTION THEREOF, METHOD FOR DESULFURIZATION, AND METHOD FOR PRODUCING HYDROGEN FOR FUEL CELL

WIPO Patent Application WO/2004/080588

A1

A desulfurizing agent, characterized in that it is represented by the general formula: ZnFe₂O₄/SiO₂/a molybdenum compound (MoS₂ and/or MoO₃), or ZnFe₂O₄/SiO₂/a molybdenum compound (MoS₂ and/or MoO₃)/a titanium compound(TiO₂); a method for producing the desulfurizing agent; a desulfurizing method which comprises contacting a sulfur-containing compound with the desulfurizing agent; and a method for producing a highly pure and highly desulfurized hydrogen gas which comprises the desulfurization using the desulfurizing agent followed by a reforming treatment. The desulfurizing agent exhibits high performance capability and allows sulfur to be removed from a sulfur-containing compound instantaneously in an one stage process with high efficiency, and also can be regenerated and used repeatedly. Further, the desulfurization using the desulfurizing agent can be temporarily stopped. The above method for producing hydrogen can be employed for producing a hydrogen gas for use in a fuel cell on a large scale at a low cost.
