(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.
