Title:
FUEL REFORMING SYSTEM
Document Type and Number:
Japanese Patent JP3778038
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a start-up method for a fuel reforming system which can start in a short time while avoiding hydrogen embrittlement.
SOLUTION: The fuel reforming system is provided with a membrane reactor 2 formed of a reforming catalyst part 4 to carry out a reforming reaction of a supplied fuel gas, a hydrogen separation membrane 5 and a hydrogen path 6 for taking hydrogen out of a reforming gas and a combustion catalyst part 3 to heat the reforming catalyst part 4 by combustion of a discharged gas and a fuel; a combustor 14 to generate a combustion gas for heating the membrane reactor 2; and a means 16, 17 for detecting or estimating a temperature of the hydrogen separation membrane 5. The combustion gas is supplied to at least one of the reforming catalyst part 4 and the hydrogen path 6 in the membrane reactor 2 at start-up, and when the temperature of the hydrogen separation membrane 5 reaches a predetermined value or higher, the supply of the combustion gas is stopped and the reforming reaction is initiated.
