Analysis on Each Characteristic of Biogas Dry Reforming Membrane Reactor to Supply H₂ for SOFC

Abstract

The aim of this study was to clarify the characteristics of biogas dry reforming to produce H₂ by two-dimensional numerical simulations using COMSOL Multiphysics. The impact of the porosity of catalyst as well as the thickness of H₂ separation membrane on the characteristics of biogas dry reforming, i.e., the distribution of molar concentration of each gas, gas velocity, and gas pressure in the membrane reactor, was investigated. The highest concentration of produced H₂ was obtained for the porosity of catalyst of 0.1 and the thickness of H separation membrane of 20 μm, indicating that this is the most optimum condition for the biogas dry reforming process.
