摘要
利用沸程在100-200℃的乙烯装置副产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物质量分数1．0％、三氯化铝质量分数1．5％、聚合温度60℃、聚合时间6h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号溶剂油，指标达到行业标准。
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.
