(544fd) Dry-Reforming of Methane over M/Ni-M/Al2O3-CeO2 (M =Pt, Fe, Mg, and Mo) Catalysts

The dry reforming of methane (DRM) converts two major greenhouse gases into a synthesis gas with H₂:CO ratio of close to 1 and, thus, can be used readily for Fischer-Tropsch and carbonylation reactions. Transition metals catalysts such as Ni, Co, Pt, Ru, Rh, and Pd with various supports such as Al₂O₃, MgAl₂O₄ or La₂O₃ are used for the DRM. In this work, we synthesized M/Ni-M based bi-metallic catalysts (M = Fe, Mg, Mo and Pt) over Al₂O₃-CeO₂ supportand evaluated their catalytic performance for dry-reforming of methane. The catalysts were characterized employing XRD, XRF, H₂-TPR, pyridine FTIR, and N₂ physisorption techniques. The Mg/Ni-Fe/Al₂O₃-CeO₂ catalyst showed higher catalytic stability and performance at 700 ^oC for 10 h time on stream.
