摘要： 利用沸程在100～200 ℃裂解乙烯的副产C9馏分为原料，研究了以Lewis酸为催化剂的两段聚合法制备芳烃溶剂油的工艺条件。主要考察催化剂用量、聚合温度、聚合时间对产品分布的影响。结果表明，采用两段聚合法，在催化剂三氟化硼乙醚络合质量分数1.0%、三氯化铝质量分数1.5%、聚合温度60℃、聚合时间6 h的条件下，芳烃溶剂油收率为71.1%，石油树脂收率最高可达20%；同时所得的芳烃溶剂油切割为120号和200号，指标达到行业标准。

Abstract: The preparation of aromatic solvent naphtha by two-stage polymerization over Lewis acid catalyst was studied using C9 fraction, the by-product of ethylene cracking unit, as feedstock. The effects of catalyst dosage, reaction temperature and reaction time on the product distributions were investigated. Results showed that under the conditions of a reaction temperature of 60℃, a reaction time of 6 h and a catalyst consisted of 1.0% BF3-ether and 1.5% AlCl3, the yields of aromatic solvent naphtha and petroleum resin reached 71.1% and 20%, respectively. The qualities of the obtained solvents (cut to 120# and 200#) could meet the requirements of trade standard SH0005-90.
Key words: C9 fraction, Aromatic solvent naphtha, 120# solvent naphtha, 200# solvent naphtha, Petroleum resin
