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).
