Abstract
In this research, the authors examine n-dodecane as a heavy-hydrocarbons fuel, which is a main constituent of kerosene. Then, the authors develop a small and simple steam-reforming reactor in a home-use size, for a fundamental study. The authors measure the hydrogen-molecule ratio R_<H2> together with the molecule ratios R_<CO>, R_<CO2> and R_<CH4> of other main gass components such as CO,CO_2 and CH_4 using a gas chromatograph, respectively. In addition, the authors conduct numerical simulations based on the thermal-equilibrium theory, and reveal R_<H2>, R_<CO>, R_<CO2> and R_<CH4>, as well as experiments. As a result, the authors successfully achieve suitable inside-temperature profiles, by the control of a thermal diffuser. The effects of the steam-to-carbon ratio S/C upon R_<H2> R_<CO>, R_<CO2> and R_<CH4> are shown, experimentally and theoretically. The experimental results agree with the theoretical ones qualitatively, but not quantitatively especially for R_<H2> and R_<CH4>.
