We have been studying about the new power generation systems for C0_2 recovering based on combined 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. The residual gas including CH_4 and CO is combusted at the after burner with pure oxygen, and high concentration C0_2 is exhausted directly. These systems apply the high temperature inorganic hydrogen separation membrane such as multi-1ayers porous ceramic membrane. HYDET System I has the membrane reformer at combustion chamber. The performance of System I reaches 50% HHV at the sending end by the effect of recupering gas turbine cycle. C02 recovery will depend upon permeability of the membrane, theoretically it will be 100%. And by using C0_2 Iiquefaction equipment of LNG cold heat exchanger, Iiquid CO_2 will be recovered with extra high efficiency. To apply these systems, key technology is the development of the high temperature inorganic hydrogen separation membrane.
