Title:

DESULFURIZING AGENT AND METHOD OF DESULFURIZATION WITH THE SAME

Document Type and Number:

WIPO Patent Application WO/2006/101079

Kind Code:

A1

Abstract:

A desulfurizing agent with which sulfur components contained in a raw hydrocarbon and/or oxygenous raw hydrocarbon can be efficiently removed to an extremely low concentration and which has a long life and is industrially advantageous; a process for producing hydrogen for fuel cells which comprises subjecting a raw hydrocarbon and/or oxygenous raw hydrocarbon desulfurized with the desulfurizing agent to steam reforming, partial-oxidation reforming, or autothermal reforming; and a fuel cell system employing the hydrogen produced by the process. The desulfurizing agent, which is for removing sulfur compounds from a raw hydrocarbon and/or oxygenous raw hydrocarbon, comprises silicon and either nickel or nickel and copper and has a bulk density of 0.95-2.0 g/cm³, pore volume of 0.10- 0.40 ml/g, micropore surface area of 100-250 m²/g, and external-surface area of 100 m²/g or smaller. The process for producing hydrogen for fuel cells employs the desulfurizing agent.
