Abstract

Two different catalysts, Ni-(ZrO2) and Ni-(La2O 3)0.1-(ZrO2)0.9, were synthesized to use as catalysts in the autothermal reforming of methane. Ni-(ZrO2) catalyst without lanthanum prepared in this study has a good initial performance, but as the reactions keep progressing, the activities gradually decrease. In contrast, the activities of Ni-(La2O3) 0.1-(ZrO2)0.9 catalyst have high thermal stability and coke resistance due to the presence of La. Both methane conversion and hydrogen yield of Ni-(La2O3)0.1-(ZrO 2)0.9 in non-reduced form are better than reduced form and as good as commercial Ni-based catalyst (ICI 57-4).
