英文摘要：

Carbon deposition is a key problem for carbon dioxide reforming of methane with the non-noble metal Ni based catalysts at high temperature. The performance of carbon deposition resistance of reforming catalysts was summarized. The relationships among carbon deposition resistance and oxygen carrying ability of supports, surface acidity as well as carrier structures were presented. The effects of surface acidity, metal support interaction and active component dispersion of various types of promoters modified catalysts on the carbon deposition resistance were analyzed. The relationship between particle size of nickel active component as well as dispersion of catalysts modified by some physical methods and carbon deposition resistance ability was discussed. Moreover, the problem of carbon deposition was analyzed, and the carbon deposition resistance methods of reforming catalysts were proposed. In addition, future development on coke resistant Ni catalysts for these processes was also given.
