Hydrogen Production by Autothermal Reforming of Propane Over Ni/Perovskite Catalysts Modified by Mo

Perovskite catalysts with a general formula of ABO3 exhibit high thermal stability and high oxygen storage capacity. A site metal in perovskite structure has a strong effect on thermal stability, while B site metal in perovskite structure acts active site. And it is well known that Mo metal is important material of Water Gas Shift reaction and Hydrogen production. So, to find optimum ratio of Mo, various ratio of Mo modified Ni/perovskite catalysts were tested. In this study, Mo modified Ni/perovskite catalysts were prepared by citric acid method of Sol-gel method. Ni(10wt%)-Mo(Xwt%)/LaFe0.5Ni0.5O3 perovskite catalysts (X=1, 5, 10,) were tested in constant pressure flow reactor with the reactant ratio of H2O/C3H8/O2=8.96/1.0/1.1. XRD, CO chemisoption, TGA, TEM and SEM were used to investigate morphologic construction, dispersion of metal, carbon deposition analysis, respectively.
