NOVELTY - A reactant gas mixture (40) is contacted with catalyst(s) under conditions, where the reactant gas mixture is partly reformed into a product gas mixture (42) containing a synthesis gas, and solid carbon particles are formed over two-dimension carbon sequestration catalyst(s). The reactant gas mixture comprises carbon dioxide and an organic material. The product gas mixture and solid carbon particles are then recovered.    USE - For carbon sequestration and dry reforming for production of synthesis gas used as fuel for fuel cell.    ADVANTAGE - The carbon sequestration and dry reforming process enables sequestering carbon from carbon dioxide for reducing green house effect gas emissions. The catalyst used in the process is capable of reforming organic gases to carbon monoxide and hydrogen, by generating carbon deposits.    DETAILED DESCRIPTION - A reactant gas mixture is contacted with at least one catalyst under conditions, where the reactant gas mixture is at least partly reformed into a product gas mixture containing a synthesis gas, and solid carbon particles are formed over at least one two-dimension carbon sequestration catalyst. The reactant gas mixture comprises carbon dioxide and an organic material. At least one catalyst for dry reforming the reactant gas mixture and sequestering carbon, is two-dimensional carbon sequestration catalyst. The product gas mixture and solid carbon particles are then recovered by carbon sequestration and dry reforming process. INDEPENDENT CLAIMS are also included for the following:    (1) filamentous carbon material resulting from the carbon sequestration and dry reforming process;    (2) synthesis gas resulting from carbon sequestration and dry reforming process;    (3) carbon sequestration method in dry reforming process, which involves contacting the reactant gas mixture and dry reformed gas, with two-dimension carbon sequestration catalyst at a temperature at which the solid carbon deposit is formed at the surface of catalyst;    (4) carbon sequestration and dry reforming reactor, which consists of at least one housing, catalyst(s) disposed in at least one of the housing for dry reforming the reactant gas mixture circulating into product gas mixture and sequestering carbon, and a heater. At least one housing has gas input(s) and gas output(s). The gas input(s) is adapted to receive the reactant gas mixture. At least one of the catalyst is two-dimension carbon sequestration catalyst. The heater is operatively connected to the reactor for heating at least one of the gas mixture and at least one catalyst;    (5) reforming catalyst comprising an active metal deposited on one of a non-porous support. The non-porous support is chosen from a non-porous metallic support and a non-porous ceramic support. The active metal is chosen from nickel, platinum group metals promoted nickel, alkali-enhanced nickel, copper-promoted nickel and tin-promoted nickel; and    (6) two-dimension reforming catalyst manufacturing process, which involves depositing the catalytic metal precursor over the non-porous support.
