摘　　要：采用浸渍法制备了负载型Ru-Y/Ti O_2催化剂,并考察了其在萜烯树脂加氢反应中的催化性能。结果表明,负载型Ru-Y/Ti O_2催化剂对萜烯树脂加氢反应具有较高的催化活性,在150℃,氢气压力4 MPa,反应时间6 h,制得了无色或浅色萜烯树脂,加氢反应前、后萜烯树脂的色差可达82%以上,且催化剂稳定性较好,循环使用5次后,其催化萜烯树脂加氢反应前后的色差仍高于75%。合成的无色或浅色萜烯树脂具有无毒、稳定和抗老化等特性,可广泛应用于塑料、油墨、涂料、黏合剂、电子产品、食品加工和医药材料等领域。The supported Ru-Y/Ti O_2 catalysts was prepared by impregnation and characterized by XRD and SEM.The catalytic activity on the hydrogenation of terpene resin to colorless terpene resin was explored. The results indicated that,the hydrogenation of terpene resin exhibited higher activity under the optimal reaction conditions as： terpene resin 1. 000 g,2. 5%Ru-2. 5%Y/Ti O_20. 040 g,n-hexane 2 m L,150℃,4 MPa,6 h. Color-difference of terpene resin was up to 82. 7% before and after hydrogenation. Moreover,the products were conveniently separated from the catalyst by simple decantation,and the catalyst could be reused five times,the color-difference of terpene resin is higher 75%before and after hydrogenation.The decolorized terpene resins might be used as plastics,printing inks,paintings,adhesive,electronic products,food processing and health goods because it was innocuous,stable and aging-resistant.
