PREPARATION AND CATALYTIC EVALUATION OF CATALYSTS FOR WATER GAS SHIFT REACTION FOR CO REMOVAL FROM REFORMED FUELS

A series of Cu-based mixed oxides was investigated for the development of active Cu catalysts for the "water gas" shift reaction (WGSR). Tri-metallic catalysts active for WGSR were obtained after high temperature calcination at 900 degrees C and subsequent reduction. The results were compared with commercial Cu/ZnO/Al(2)O(3) catalyst and prepared Ru/TiO(2)/Al(2)O(3) catalyst. The prepared catalysts were characterized by temperature programmed reduction, XRD, and sorption analyzer. Near equilibrium conversion of CO was achieved by the prepared catalysts around 250 degrees C. The Ru-based catalyst showed maximum CO conversion around 300 degrees C with some methanation activity, whereas Cu-based catalysts produced a negligible amount of methane in the product stream.
