TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The carbon sequestration and dry reforming process further involves mechanical withdrawing the solid carbon particles, adding steam to the reactant gas mixture, and activating the catalyst by pre-heating the catalyst under inert gas flow. Dry reforming of the reactant gas mixture is carried out on a three-dimension catalyst at a primary reaction temperature, and sequestering of the carbon is carried out on at least one of two-dimension catalyst (24) at secondary temperature. At least one of the catalyst comprises active metal deposited on one of the non-porous support. The product gas mixture is a fuel for fuel cell. The reactant gas mixture is an output product of fuel cell. The two-dimension carbon sequestration catalyst comprises iron-based superficial catalytic material activated by heating under inert gas atmosphere to 700-900degreesC. The inert gas is nitrogen. Preferred Condition: The two-dimension catalyst is heated to a temperature higher than the eutectic point, and steel is transformed to its alpha-phase. Preferred Composition: The organic material and carbon dioxide in the reactant gas mixture are in molar ratio of 0.3-3. The two-dimension carbon sequestration catalyst comprises an activated iron-based catalytic material, which comprises nickel, chrome and/or cobalt alloying elements. The iron-based catalytic material is a high temperature resistant iron alloy. The reforming catalyst is a dry reforming catalyst or two-dimension catalyst. The catalyst is obtained by impregnation of non-porous support using one of nitrate salts and chloride salts of active metal, and by thermal plasma deposition on support using nitrates, carbonates or chlorides of active metal. The catalytic metal precursor is nitrate, carbonate or chloride. Preferred Support: The non-porous support is a ceramic support chosen from alumina, zirconia and phosphate oxide, or is a metallic support comprising fritted molybdenum.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Reactor: The reactor consists of at least two housings (I, II). Housing (I) consists of three-dimension dry reforming catalyst. Housing (II) consists of two-dimension carbon sequestration catalyst(s). The reactor is operable in at least one of solid carbon recovery mode and catalyst regeneration mode.
