摘要：

This paper presents a performance analysis of a dual-bed autothermal reformer of methane for hydrogen production. The first section of Pt/Al2O3 catalyst is designed for oxidation reaction, whereas the second one involves steam reforming reaction based on Ni/MgAl2O4 catalyst. A one dimensional, non-isothermal reactor model was employed to examine the reformer performance regarding important operating conditions such as H2O/CH4 feed ratio; O-2/CH4 feed ratio, temperature and location of steam feed. The simulation results indicate that when the dual-bed reformer was operated at the H2O/CH4 feed ratio of 1.0-2.0 and O-2/CH4 feed ratio of 0.45-0.60, the methane conversion of 93% and the H-2/CO product ratio of higher than 2.9 were obtained. In addition, it was found that adding steam at lower temperatures to the steam reforming section of the dual-bed reformer can produce the synthesis gas with a higher H-2/CO ratio.
