摘要：
The CO2 reforming reactions of methane were carried out using three types of Ni/-Al(2)O(3)s and the effects of the addition of CeO2 were examined. In this study, the addition of a high weight percentage of CeO2 focused on reducing the amount of deposited carbon. It was revealed that a high Al2O3 surface area was necessary for the effective reduction of the deposited carbon by the addition of 50% CeO2 with the lowest conversion decrease. The addition of CeO2 and ZrO2 (Ni/Al2O3(A)-CeO2(45)-ZrO2(5)) further decreased the deposited carbon to 0.14mmol per 1mol of produced CO at 1073K. [GRAPHICS] .
