Development of a stable nickel on alumina catalyst for the carbon dioxide reforming of methane.

Ni (10.6 wt.-%) supported on gamma alumina obtained through a sol-gel techn ique, and reduced at high temperature (> 1100 K), was found to be an active and stable catalyst for the carbon dioxide reforming of methane. The catal yst kept its activity for 100 h or longer at 973 K, giving little coke on t he catalyst (< 1 w.-%). The measured conversion data were fitted with a pse udo homogeneous model.
