摘　　要：化工分离技术是化工行业基础的实验和应用技术,本文采用不同的分离方法对碳九馏分进行分离探究,确定了带侧线出料的连续解聚-精馏的工艺,在优化的操作条件下,塔顶可得到环戊二烯含量98%以上馏分,在侧线馏出口可得到混合馏分,环戊二烯和甲基环戊二烯总含量在95%以上,两种组分的收率均可达76%以上。不同分离方法的探究将会对化工专业精馏教学形成有益的补充。Chemical separation technology is the basic experiment and application technology in chemical industry. In this paper, different separation methods are explored to separate C9 fraction, and the continuous depolymerization-distillation process with side stream discharge is determined. Under the optimized operating conditions, more than 98 % cyclopentadiene fraction can be obtained at the top of the tower, and mixed fraction, cyclopentadiene and methylcyclopentadiene can be obtained at the outlet of side stream with the total content is above 95 %, the yield of each component is above 76 %. The exploration of different separation methods will form a beneficial supplement to the distillation teaching of chemical engineering specialty.
