Catalytic Performance of Dimethyl Ether Combustion over La-Ce-Cu/Al₂O₃ Catalysts

Abstract:

kinds of Al2O3 were synthesized by using aluminum nitrate as the aluminum source, glucose, lactic acid and citric acid as templates respectively. It is showed that all Al2O3 were mesoporous materials due to their BET surface area results. The Al2O3-glu, synthesized by using glucose as a template, demonstrated fine pore shape, larger surface area and pore volume. The Ce0.1Cu0.9O1.1/Al2O3-glu catalyst exhibited good performance for dimethyl ether(DME) Combustion. La-doping can promote its catalytic activity. Over La0.4-Ce0.1Cu0.9O1.1/ Al2O3-glu catalyst, the DME combustion temperature(T10) was 493 K and the complete combustion temperature(T90) was 498 K. The life test result indicated its catalytic activity without any reduce even after 100 h reaction.
