通过对C5石油树脂的催化加氢，合成了浅色度C5石油树脂，制备并筛选了催化剂，采用固定床反应器对C5石油树脂进行了加氢工艺研究，采用BET、SEM和DTA-TG对催化剂进行了表征，用IR对C5石油树脂加氢前后的结构进行了分析。研究结果表明，Ni基多金属催化剂 C5JH-3在原料浓度为20%、温度为220～240℃、压力3.5MPa、空速0.5h-1、氢油比600∶1的条件下对C5石油树脂加氢，可制得软化点高的浅色度树脂。

To obtain light-colored C5 petroleum resin , C5 petroleum resin was catalytically hydrogenated in a fixed-bed hydrogenation micro reactor. The C5 petroleum resin hydrogenation process was studied. Several hydrogenation catalysts were prepared and compared. The catalysts were characterized by nitrogen adsorption-desorption (BET),scanning electron microscopy (SEM) and differential thermal analyzer (DTA-TG). The petroleum resin and hydrogenated petroleum resin were characterized by FT-IR spectroscopy. The high softening point and light-colored C5 petroleum resin was obtained under the condition of Ni multi-metal catalyst C5JH-3,raw resin concentration of 20%, temperature of 220-240℃,pressure of 3.5MPa,space velocity of 0.5h-1,and hydrogen to oil ratio of 600∶1.
