Five nickel catalysts on different supports were studied for methane reforming with CO2. Although all catalysts almost reached equilibrium conversion, the content of carbon deposition differed widely from each other. The effect of supports on carbon deposition of nickel catalysts was investigated. The acid-base property of catalysts characterized by TPD and XPS was correlated with the content of carbon deposition. With the increase in base strength of catalysts the content of carbon deposition decreased.
