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. In a previous study (Fujimoto et al., 2011), it have been experimentally shown that the effects of the liquid-hourly space velocity LHSV upon C_<H2>, C_<CH4>, C_<CO> and C_<CO2>, where conversion ratio becomes low at high LHSV's ≥ 1.0 h^<-1>. Thus, at LHSV = 1.0 h^<-1>, the authors reveal the effects of the temperature T inside the reactor upon the molecule ratios, comparing with a thermal-equilibrium theory.
