The Performance of the Cu-Zn/CeO₂ Catalysts in the Steam Reforming of Methanol Reaction

Abstract:

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.
