摘要
催化剂载体是加氢脱芳(HDA)研究的重要内容,20世纪80年代以来,复合载体受到了极大的关注。综述了近年来贵金属深度加氢脱芳催化剂载体(负载贵金属Pd和Pt)的研究进展。主要介绍了含A12O3、TiO2及SiO2的复合氧化物载体的催化剂在芳烃加氢过程中表现出的加氢活性和抗硫性。无论从催化剂的催化活性,还是抗硫性能方面比较,复合氧化物载体的催化剂都表现出良好的性能,尤其是三元复合氧化物载体的催化剂,比其他更加稳定,具有更好的催化性能。
Supporters are important aspect of hydro-dearomatization （HDA） studies and composite oxide supporters attract many attentions in the last two decades. The recent developments in researches on supporters of catalysts （supported Pd and Pt） used in deep hydro-dearomatization were reviewed. The hydrogenate performance and sulfur tolerance of Al2O3, TiO2 and SiO2 containing composite oxide supporters in the hydrodearomatization progress were introduced. The composite oxide supporters show good performance of catalytic activity and sulfur tolerance, especially the triple composite oxide supporters are more stable than the other catalysts and have better catalytic properties.
