英文摘要: A series of sulfur-tolerant Co-Mo/MgO-Al2O3-TiO2 catalysts promoted by TiO were prepared by kneading method and characterized by temperature-programmed reduction, temperature-programmed sulfurization and in-situ infrared spectroscopy. The catalyst activity for water gas shift reaction was tested under atmosphere in an ordinary tubular reactor. The results indicate that TiO2 promotes the activity of Co-Mo/MgO-Al2O3-TiO2 catalyst and decreases the reducing and sulfurizing temperature by changing interaction between active composition and carrier. In-situ infra-red spectra show that TiO2 decreases the saturation level of active Mo and increases the coordinate capacity of active Mo with CO.
