Catalysts for carbon dioxide reforming of methane to synthesis gas

CO2 reforming of CH4 to form synthesis gas is reviewed, and present situation in choice of catalysts, influence from support, effects from promoter and preparation methods are discussed. Differences in catalytic activity and ability to resist coking between noble metal based catalyst and Ni based catalyst are described. Several new types of supports are introduced such as Ca0.8Sr0.2TiO3, ultrafine materials and so on, their promotion effects on catalytic activity, selectivity, stability and coking resistance of catalysts are also introduced. And several new preparation methods like sol-gel supercritical drying are discussed. Promotion effects of alkaline earth metals and rare earth metals on catalytic activity and coking resistance of catalysts are also described.
