We have been studylng about the new power generation systems for C0_2 recovering based on a com-bined cycle named Hydrogen Decomposed Turbine Systems/HYDET. In these systems the natural gas is reformed and hydrogen is decomposed simultaneously from reforming gas by using membrane reformer which composed of both the reforming catalyst and the hydrogen separation membrane. HYDET System II has the membrane reformer in the heat recovery steam generator. In this system, gas turbine exhaust heat can be used for both reforming reaction and production of steam. The net effilciency, therefore, becomes over 50% HHV, which is higher than that of System I. C0_2 recovery ratio depends upon selectivity of the membrane and the cost will be affected by the permeability of membrane. To apply these systems, key technology is the development of the high temperature inorganic hydrogen separation membrane.
