Title:
DESULFURIZING AGENT, METHOD FOR DESULFURIZATION AND METHOD FOR PRODUCING HYDROGEN FOR FUEL BATTERY
Document Type and Number:
Japanese Patent JP2001279257
Kind Code:
A
Abstract:

To obtain a desulfurizing agent which can efficiently remove sulfur contents in a petroleum-based hydrocarbon and has a long life, to provide a desulfurization method by which the sulfur contents in the hydrocarbon can efficiently be removed down to a low concentration, and to provide a method for producing hydrogen for fuel batteries.

This desulfurizing agent for petroleum-based hydrocarbons, is characterized by comprising iron carried on a carrier. The method for desulfurization, is characterized by desulfurizing a petroleum-based hydrocarbon with the desulfurizing agent and, if necessary, further bringing the desulfurized hydrocarbon into contact with a second desulfurizing agent. The method for producing the hydrogen for fuel batteries, is characterized by bringing the petroleum-based hydrocarbon brought into contact with the second desulfurizing agent into contact with a steam reformation catalyst.
