We has developed a small and simple steam-reforming reactor in a home-use size for n-dodecane as a heavy-hydrocarbons fuel. The reactor satisfy the target thermal conditions by the control of a thermal diffuser. Under the conditions, we measure the inside-temperature profile, and the hydrogen-molecule ratio R_<H2> together with the molecule ratios R_<CO2>, R_<CO> and R_<CH4> of other main gass components such as CO_2 CO and CH_4, respectively, using a gas chromatography. The effects of steam-to-carbon ratio S/C upon R_<H2>, R_<CO2>, R_<CO> and R_<CH4> are shown, experimentally and theoretically. The experimental results agree with the theoretical ones qualitatively, but not qualitatively especially for R_<H2> and R_<CH4>.
