摘要: The gas-solid reaction between methane and the lattice oxygen of Mi, Co, Fe-oxides loaded on various support materials produced a synthesis gas (hydrogen carbon monoxide) at 600-800°C. Metal oxides were reduced to metals or lower valence oxides, they re-oxidized by introducing air after reaction. Thus, production hydrogen free from nitrogen can be achieved alternatively without using pure oxygen. As metal oxide, Fe 2 O 3 Rh -loaded Y exhibited highest H selectivity 60.1% with moderate CH 4 conversion 54% high utilization 84% 800 °C.
