CO2 Reforming of Methane over Ca-Modified Ni/Ce-ZrO2 Catalyst

초록

Catalytic reforming of methane with carbon dioxide to produce synthesis gas with lower H2/CO ratio is a challenging approach for the chemical utilization of natural gas and carbon dioxide; consequently, considerable effort has been devoted to the development of high performance catalysts. The new Ni/Ce0.2Zr0.8O2 catalyst reveals high activity as well as high stability in the CO2 reforming of methane. The high catalyst stability is mainly ascribe to a synegistic effect of a Ca promoter and a Ce modifier for coke resistance and high temperature catalyst aging.
