<P>PROBLEM TO BE SOLVED: To provide a method for decomposing steam, a carbon dioxide gas, a methane gas as each object gas at room temperature and under low vacuum conditions, to provide a method for directly converting a carbon dioxide gas from a mixture of a carbon dioxide gas and steam to a chemical species comprised of carbon and hydrogen, and to provide a method for reforming methane by carbon dioxide. <P>SOLUTION: The chemical decomposition and reaction promoting method to superimpose discharge on initial ablation plasma 12 emitted from the cathode in a decomposition and reaction vessel is characterized by repeating irradiation of a site to be irradiated of the cathode with pulse laser light in a state where the discharge potential of the pulse laser light is applied between the electrodes of the decomposition and reaction vessel through the constitution of an exhaust valve 1, a gas introduction valve 2 and a gas withdrawing valve 3, a decomposition and reaction vessel 6 having the cathode 4 and the anode 5 and a transparent window 11, a direct current power source 7 to supply electric power to the electrodes, and a pulse laser equipment 10 capable of repeating pulse laser light 9 sufficient to generate ablation plasma to the site 8 to be irradiated of the cathode. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
