Abstract
Carbon dioxide reforming of methane (CDR) can convert two greenhouse gases, methane can carbon dioxide, into useful syngas. Nickel-based catalysts have been extensively investigated due to their high activity and low cost. However, coke formation over Ni catalyst is serious and leads to rapid deactivation of the catalyst. Coke resistant Ni catalyst for CDR reaction is desired. In this paper, recent progresses in the design and preparation of coke resistant Ni catalysts supported on solid solutions, zeolite, perovskites and perovskite type oxides, hexaaluminates or substituted hexaaluminates, pyrochlore, montmorillonites, and hydrotalcites for CDR were summarized. The progresses in the use of promoters, in the effect of supporting materials and in the preparation methods have been discussed. The future development of coke resistant Ni catalysts for these processes is briefly addressed.
