Preparation of light-colored C5 petroleum resin by catalytic hydrogenation

Abstract

Abstract: 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.

Key words: C5 petroleum resin, catalyst, catalysis, hydrogenation

摘要： 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。
