Development of hydrogen infrastructure will become an important issue at an early, introductory, stage of fuel cell vehicle. A
steam reforming process of city gas is one of the strongest candidates of the hydrogen production since the urban area has the
city gas network to be supplied to the reformer that will be built in hydrogen refueling station. Enhancement of hydrogen
production efficiency at reforming process is the most important issue for accelerating the hydrogen use. To improve the
conversion of methane to hydrogen and capture the CO2 emission from product gas, non-equilibrium reforming process with
CO2 absorbent and regeneration under reduced pressure condition were proposed. The maximum efficiency in the
non-equilibrium reforming process was expected to be achieved 75 % with the reduced pressure regeneration since the heat
recovery at combustor and the sensible heat from regenerated CaO effectively used for the endothermic reaction in the
hydrogen production process. The experiment with adsorbing and the regeneration in reduced pressure less than 0.006 atm
shows possibility of the regeneration at 630℃.
