Book excerpt: The utilization of carbon dioxide reforming of methane in a solar based Chemical Energy Transmission System (CETS) relies greatly upon the development of suitable catalysts for both the endothermic and exothermic reactions. Carbon dioxide reforming of methane produces hydrogen and carbon monoxide at a ratio of about one, thus requiring the methanation reaction on the other side of the closed loop CETS to utilize this feed. H2/CO ratios lower than three favor the formation of carbon with industrial methanation catalysts. Preliminary tests performed on methanation with rhodium and nickel catalysts produced two, 0.5% Rh/A12O3 and Ni/A12O3, for further study. Kinetic experiments were conducted in an isothermal continuous stirred tank reactor constructed of a copper alloy which prevented carbon formation on reactor parts. These experiments were performed on pelleted 0.5% Rh/A12O3 in the 400 to 500 C range and pelleted 70% Ni/A12O3 in the 300 to 500 C temperature range. In most experiments steam was added to the reactor feed to inhibit carbon formation. Keywords: Catalytic methanation, Methanation kinetics, Carbon monoxide, Hydrogen, Rhodium, Nickel, Theses. (MJM).
