Abstract
Multiple-metal catalysts (Ni-Mn-Ce-K/bauxite) for Water-Gas Shift (WGS) reaction were prepared by impregnation, and the catalytic structure and properties were investigated by N 2 physical, XRD, H 2-TPR, and CO-TPD. The results indicated that the addition of 7.5% CeO 2 improved the activity of the WGS reaction obviously, and also increased the specific surface area and pore volume of the catalysts. The addition of CeO 2 decreases the reduction temperature, enhanced the adsorption and activation of H 2O, and improved the adsorption content of CO. Besides, active sites were not changed and the number of active sites on catalysts did not increase obviously.
