摘要
以中国石油抚顺石化公司石油一厂焦化柴油210~270℃馏分油为原料,以三氯化铝与三氯甲烷的复合物为催化剂,进行焦化柴油烷基化研究。考察了催化剂用量、反应温度、反应时间、苯烯比对烷基苯收率和烷基化油质量的影响。结果表明,采用三氯化铝复合催化剂,在催化剂质量分数为5%、反应温度为60℃、苯烯摩尔比为8、反应时间为6 h的条件下,烷基苯收率达到19.6%,烷基化油的质量明显优于焦化柴油。
The alkylation of coker gas oil over a combined catalyst, aluminum trichloridetrichloromethane,was studied using coker gas oil from the No. 1 Refinery of PetroChina Fushun Petrochemical Company with a boiling range of 210-270℃. The effects of catalyst dosage,the ratio of benzene to olefin,reaction temperature and reaction time on the yield of alky-benzene and the quality of alkylate were investigated. Results showed that using aluminum trichloride combined catalyst under the conditions of a catalyst dosage of 5 %,a benzene/olefin molar ratio of 8, a reaction temperature of 60 ℃ and a reaction time of 6 h, the yield of alky-benzene reached 19. 6% and the quality of the obtained alkylate was significantly improved as compared with coker gas oil.
