CO2 reforming of methane over zirconia-supported nickel catalysts, I. Catalytic specificity

CO2 reforming of methane is performed over zirconia-supported nickel catalysts. The catalysts show high activity toward CH4 and CO2 conversions. Over the high Ni loading catalyst, long-term performances without significant deactivations have been achieved at 1023 K for 30 h and 1123 K for 20 h, respectively. The effects of reduction and calcination temperatures on the catalytic activities are also examined.
