Catalytic Activity and Stability of Nickel-Modified Molybdenum Carbide Catalysts for Steam Reforming of Methanol

The performances of different xCu10Ce and xZn10Ce (x = 1, 3, and 5) catalysts prepared by impregnation method then pelletised, were investigated in the steam reforming of methanol (SRM) under a GHSV = 15500 h-1 with H2O/CH3OH = 2. The impregnation of copper over ceria supports shows better results than that of zinc. The catalytic activity in the Cu-based depends on the dispersion of the copper species. The methanol conversion rate is related to the formation of an optimum content of reduced copper species.

Abstract The aim of the work was to investigate how the size of Ni and Cu-supported nanoparticles influence their activity in an oxidative steam reforming of methanol. The size of metal particles was controlled by the initial introduction or elimination of oxygen-containing groups on the surface of carbon nanotubes. The results of the activity tests showed that catalysts with the smallest metal nanoparticles were the least active since they easily underwent oxidation during the process.

AbstractA Ag-Au(1-D)-CeO2 catalyst was prepared by precipitation method using Ag-Au nanowires and Ce(NO3)3·6H2O as precursors. The catalytic activity of the catalysts was evaluated in a steam reforming of methanol (SRM) reaction from 250 to 475 °C. 100 % of methanol conversion was observed at 450 °C together with high H2 selectivity. This study evidenced that the use of 1-D metallic nanostructures could be used as an active phase on a CeO2 matrix for steam reforming of methanol for H2 generation to be used as fuel.
