Patent ID: 7556781

Claim:
A reformer arrangement comprising a pre-reformer and a reformer, said pre-reformer comprising a gas tight duct and at least one electrically conducting member arranged in the duct, the at least one electrically conducting member is electrically isolated from the duct, the duct has an inlet for receiving a hydrocarbon fuel at a first end and an outlet for supplying a pre-reformed hydrocarbon fuel at a second end, at least the inner surface of the duct is chemically inert with respect to the hydrocarbon fuel, an electrical power supply electrically connected to the at least one electrically conducting member and control means to control the supply of electrical current through the at least one electrically conducting member to maintain the at least one electrically conducting member at a temperature to provide selective thermal decomposition of higher hydrocarbons in the hydrocarbon fuel wherein the outlet of the duct is connected to a reformer via means to remove particulate carbon from the pre-reformed hydrocarbon fuel.
