TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The reforming reaction, which is a steam reforming reaction, occurs proximate to the membrane, and is performed with a catalyst. A compressed air (8) is supplied to the combustion zone, and heated by the combustion. The heated air and the effluent (9), which is concentrated carbon dioxide stream obtained from carbon monoxide, are used to power a turbine. A portion of carbon dioxide is recycled to the reforming zone to suppress carbon deposition.Preferred Components: The feed is steam and hydrocarbon. The effluent of reforming zone is cooled, compressed and injected into reservoir, such as geological formations and deep water, for sequestering carbon.Preferred Conditions: The reforming reaction is conducted at 400-1400 degrees C, preferably 700-1300 degrees C. The feed is provided at a pressure of 1-300 bars, preferably 5-50 bars and more preferably 5-40 bars.Preferred Reactor: The reactor comprises several modules, each having units (a-e). The unit (a) has the reforming zone, combustion zone and membrane. The unit (b) has a distribution and collection units for reforming and combustion zones. The unit (c) has several membranes. The unit (d) has flow channels between the membrane components, and the unit (e) is a sealing unit between the combustion and reforming zone.Preferred Properties: The membrane has hydrogen permeance of 1-106 moles/(m2-day-H2 atm.). The pressure of the reforming zone is higher than the pressure of the combustion zone, by 0-100 bars, or the pressure of the combustion zone is higher than the pressure of the reforming zone, by 0-50 bars.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Membrane: The membrane is fabricated from alumina, zirconia, silicon carbide, silicon nitride, magnesium oxide (MgO), titanium dioxide (TiO2), lanthanum oxide (La2O3), silica, perovskite, hexa aluminate, high nickel content alloys, Hastelloy and/or cermets. The membrane, which is an asymmetric membrane, comprises a porous support having thickness of 0.1-10 mm and pores of 0.05-30 microns, and on one side a selective diffusion layer having thickness of 100 Angstrom-500 micron. The asymmetric membrane, which is preferably a catalytic membrane, has a catalyst incorporated on either membrane surface or within or on pore structures.Preferred Catalyst: The catalyst of steam reforming reaction is chosen from noble metals and noble metal oxide, transition metals and transition metal oxide, group VIII metals, and silver, cerium, copper, lanthanum, molybdenum, magnesium, tin, yttrium, zirconium and/or zinc, preferably from nickel, nickel oxide, rhodium and/or platinum. The catalyst of membrane is incorporated into the channels of the modules, and is preferably chosen from hexa aluminates, perovskite and mixed metal oxides, metals and metal oxides of 6b,7b and 8 group elements, metal and oxides of iron, rhodium, palladium and/or platinum.
