钛促进的钴钼耐硫变换催化剂性能的研究

张新堂;纵秋云;毛鹏生;辛勤

  A series of sulfurtolerant CoMo/MgOAl2O3TiO2 catalysts promoted by TiO2 were prepared by kneading method and characterized by temperatureprogrammed reduction, temperatureprogrammed sulfurization andinsituinfrared 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 CoMo/MgOAl2O3TiO2 catalyst and decreases the reducing and sulfurizing temperature by changing interaction between active composition and carrier.Insituinfrared spectra show that TiO2 decreases the saturation level of active Mo and increases the coordinate capacity of active Mo with CO.……
