Abstract
Steam methane reforming is one of the most popular methods for fuel hydrogen production. Although the commercial steam reforming usually operates under high pressure conditions, experiments for research are mainly under atmospheric. In this study, we evaluated the pressure effect of surface steam reforming reaction by experiments operated with an annular (concentric double circular) channel tube reactor. This flow channel can avoid the effects of side walls in contrast with the experiment with different pressure, the rate equation was evaluated. Finally, the obtained reaction rate was applied for numerical simulation to confirm the validation.
