摘　　要：以氢氧化铝干胶和偏钛酸为主要原料制备了Al2O3-TiO2载体,采用等体积浸渍法制备出一系列不同TiO2含量及不同配体改性的CoMo/Al2O3-TiO2催化剂;采用BET,XRD,TPR,HRTEM等方法对所制备的催化剂进行了表征,在10mL固定床评价装置上对所制备的两个系列催化剂进行了FCC汽油选择性加氢脱硫活性评价。结果表明,载体中TiO2的质量分数为10%、浸渍液中添加乙二醇和磷酸改性的催化剂具有较高的加氢脱硫活性和选择性。Ti modified alumina carriers were prepared with metatitanic acid and aluminium hydroxide dry powder.CoMo Al 2O 3-TiO 2 catalysts with different Ti content and different ligands were made by isometric immersion method respectively,and were characterized by XRD,BET,TPR and HRTEM techniques.The selective hydrodesulfurization activities of the catalysts were evaluated in a 10mL fixed-bed micro-reactor.The results showed that the catalyst having 10%TiO 2 in carrier and using glycol modifier has higher HDS activity and selectivity.
