Combustion of Methane and Carbon Monoxide over Alumina-supported Catalysts for the Purpose of the Synthesis Gas Combustion
In co-generation of methanol and electricity systems, complex component and thermal NOx puzzles the combustion of the synthesis gas. To stabilize the combustion, 45 kinds of γ-alumina-supported catalysts have tested in a fixed bed quartz reactor. The results show that Pd, Cr, Cu, Mn, Co, Fe and Ce catalysts have high activity during methane combustion. The proper active metal amount is 15 ％Cr, 15％Cu, 15％Mn, 10 ％Fe and 30％Ce in weight. Compare with non catalytic combustion, the 10％ conversion temperature (T10) can decrease 200-500K and 90％ conversion temperature (T90) decrease 100-450K. Moreover, the CO productive rate in methane combustion is decreased from 40％ to less than 7％. In CO oxidation, T10 decreases 350-550K and T90 decreases 140-550K. The following reaction order has established for the combustion of the synthesis gas: PdCoCrCuFeMn.
