PROBLEM TO BE SOLVED: To synthesize hydrogen, carbon monoxide and a hydrocarbon-based material by irradiating an aqueous solution of carbonate with radioactive rays. SOLUTION: A vessel 4 housing a source 3 of radioactive rays is immersed in an autoclave 1 with an inserted aqueous alkali solution. Carbon dioxide is injected into the aqueous alkali solution through a carbon dioxide-injecting tube 2, and the resultant solution of a carbonate is irradiated with radioactive rays to provide the objective hydrogen, carbon monoxide and a hydrocarbon- based material. An aqueous solution containing one or more kinds of catalysts selected from a metal, a metal oxide, a metal chloride and a metal nitrate can be also continuously fed to the aqueous carbonate solution. Cobalt 60, or the like, and a radioactive waste can be used as the radioactive source, and the radioactive waste generated from a nuclear power plant and the site for medical treatment can be used as the radioactive waste. Concretely, Cu, Ni, Al, CuO, Fe2O3, Fe3O4, Al2O3, TiO2, FeSO4, Fe2(SO4)3, CuCl, CuSO4, NiSO4, MnCl2.4H2O, Co(NO3)2, or the like, is exemplified as the catalyst.
