Autothermal reforming of propane over Ce modified Ni/LaAlO3 perovskite-type catalysts

Abstract

In this study, Ce modified Ni/LaAlO3 Catalysts Were prepared for propane autothermal reforming in order to increase the thermal catalyst stability and decrease the level of carbon deposition. In the Ce modified Ni/LaAlO3 catalysts with different Ce loadings, the Ni-Ce/LaAlO3 catalyst containing 5% Ce showed the highest reforming performance at high temperatures. Ce loading on the perovskite-type catalysts increased the thermal catalytic stability and decreased the level of carbon deposition during the autothermal reforming of propane. The influence of reaction temperature on the product showed that the CO concentration level could keep a low level when reformed at lower temperature. The propane autothermal reforming over the Ce modified perovskite-type catalysts showed high reforming performance due to the low carbon deposition on the catalyst surface. (C) 2009 Elsevier B.V.
