Abstract

This paper is devoted to the investigation of the steam methane reforming process in a microchannel reformer over a Ni-based catalyst. The composition of reforming products and temperature at a reformer outlet was measured experimentally as well as with the help of CFD-modeling and numerical study. The presented new direct numerical method for modeling of steam methane reforming. The study of steam methane reforming was performed for the inlet temperatures (T_in) of 600–1000 K, for Re = 10, 50, 100, and heat flux through the walls of q_w = 1000 W/m² and q_w = 500 W/m². It was found that the methane conversion in the reformer decreases with increasing Reynolds number, heat flux through the wall, and inlet temperature. For Re = 10, q_w = 1000 W/m² and T_in = 1000 K the methane conversion is 39% while equilibrium methane conversion is 63%. The temperature profiles in the reaction zone were determined. The temperature of the reaction mixture monotonically increases for all Reynolds numbers.
