Pilot Plant Study for 160 kg/h C_(16)-C_(19) Re-Alkylene Alkylation Process

采用氢氟酸烷基化法(UOP法),对C16-C19的重烷烯烃进行烷基化实验,取得相关工艺数据,开发重烷烯烷基化中试工艺技术,为工业化提供相关基础数据。当反应温度为50℃,压力为0.88 MPa,反应时间为20min,苯烯物质的量比为8∶1,HF和碳氢化合物的体积比为2∶1时,得到其最佳转化率为10.4%。

With the method of hydrofluoric acid-alkylation（the UOP method）, re-alkylene（C16-C19 ） was reacted. By this reaction, the relevant process data was obtained, the alkylation pilot technology was developed, and the underlying industrialized data was provided. When the reaction temperature is 50 ℃, the reaction pressure is 0.88 MPa, reaction time is 20 min, the amount of substance ratio for benzene and heavy hydride olefinic is 8 ： 1 and the volume ratio for HF and hydrocarbon is 2 ： 1, the conversion rate can be the best for 10.4%.
