Abstract

The suitability of zirconia-based nickel catalysts for the CO₂ reforming reaction has been investigated with emphasis on the stability of the catalysts under conditions favourable towards carbon formation. It has been found that between 720°C–780°C catalysts having lower loadings of nickel (< 2wt%) are more stable than those with higher nickel contents at stoichiometric CO₂/CH₄ ratios. Two forms of deposited carbon were observed for the less stable catalysts, whereas more stable catalysts had only one form of deposited carbon.
