Biogas dry reforming experiments were performed using membrane reactors with Ni/Cr and Ni/Cr/Ru catalysts as well as a Pd/Cu membrane for H2 separation. H2 yield and energy efficiency of the membrane reactors were investigated by varying the catalyst type, reaction temperature, pressure difference between the reaction and sweep chambers, inlet gas molar ratio, and with and without sweep gas. In this research, the CH4 and CO2 conversion rates, H2 yield, H2 permeation rate, H2 and CO selectivity, thermal efficiency, and H2 permeation flux were evaluated. As a result, H2 yield and thermal efficiency for Ni/Cr/Ru catalyst increase 0.241% and 3.31%, respectively compared to the Ni/Cr catalyst. The concentration of produced H2 using Ni/Cr/Ru was higher in than using Ni/Cr by 2871 ppmV.
