dc.description.abstractLow temperature water gasshift catalysts containing 1.0% by weight of alkali elements (Li, K, Rb and Cs) were prepared by impregnation of a ternary Cu/ZnO/Al2O3 (CZA) base catalyst. The calcined precursors were characterized by different physical and chemical techniques such as Xray diffraction, Xray fluorescence, N2O chemisorption, N2 adsorption at low temperature and Xray photoelectron spectroscopy. Then these precursors were activated and tested in the low temperature water gasshift reaction (LTWGS). It was shown that the Kcontaining CZA catalyst exhibited the highest CO conversion level at reaction temperature within the range 450–530 K. In addition, the alkali promoters were found to prevent methanol production at temperatures higher than 480 K.pt_BR
