The authors develop a small and simple steam-reforming reactor in a home-use size for n-dodecane as a heavy-hydrocarbons fuel. Under the thermal condition controlled by electric heaters and a gas burner with a thermal diffuser, the authors measure the inside-temperature profile and the hydrogen molar fraction (concentration) C_<H2>, together with the molar fractions C_<CH4>, C_<CO> and C<CO2> of other main gas components such as CH_4, CO and CO_2, respectively. As a result, the authors successfully achieve suitable inside-temperature profiles. And, the effects of the liquid-hourly space velocity LHSV upon the molar fractions and a conversion ratio X_<C12H26>, experimentally. Furthermore, the authors reveal the effects of the temperature T inside the reactor upon them molar fractions, comparing with the thermal-equilibrium theory in a wide range of LHSV. In addition, this study examine the effect on the conversion ratio X_<CnHm> of various Heavy Hydrocarbon fuels.
