The authors develop a small and simple steam-reforming reactor in a home-use size for such various heavy-hydrocarbons fuels as n-octane, n-decane, n-tetradecane and n-hexadecane in addition to n-dodecane. 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 CH4₂ , CO and CO₂ , respectively. As a result, the authors successfully achieve suitable inside-temperature profiles. And, the authors reveal the effects of the liquid-hourly space velocity LHSV upon the molar fractions, a conversion ratio X_C12H26 and reforming efficiencies for various heavy-hydrocarbons, which suggest the common upper limit of LHSV for the practically-suitable operation.
