Progress in Ni-based catalysts for CH4-CO2 reforming reaction
CH4-CO2reforming has attracted growing attention because it can efficiently utilize two greenhouse gases and convert them into valuable syngas with low H2/CO ratio.Ni based catalysts have been extensively investigated for their high activity and low cost, but they also suffer from coke deposition and sintering problems.In this paper, recent progresses in Ni-based reforming catalysts are summarized and analyzed taken into account reaction kinetics, reaction thermodynamics and formation mechanism of carbon deposition, with a particular emphasis over promoters and their roles.Finally, the bottleneck and future development trend of the titled reaction are briefly described.
