摘　　要：环戊二烯(CPD)是裂解碳五中的重要组分,也是新材料领域的重要单体。为实现CPD单体的高效提纯,采用Aspen软件搭建反应及分离全流程模型,通过后二聚法制备粗双环戊二烯(DCDP),通过气相解聚法制备高纯DCPD,实现了多品级DCPD制备工艺路线的设计,包括聚酯级、高纯级和聚合级DCPD,DCDP质量分数最高可达99.8%,收率可达92.5%以上。从而验证了该流程在工业应用上的整体可行性,并对主要设计参数及操作条件进行了灵敏度分析,得到了较优的设计及操作条件。Cyclopentadiene(CPD)is an important component among cracking C5 fractions and a crucial monomer in the advanced materials field.To achieve efficiently purifying CPD monomer,Aspen software is utilized to construct a whole process model for the corresponding reaction and separation.Crude dicyclopentadiene(DCDP)is prepared through the post-dimerization method,and high-purity DCPD is prepared via the vapor-phase depolymerization method.Therefore,a multi-grade DCPD preparation process route is designed,including polyester-grade,high-purity grade,and polymerization-grade DCPD.The purity of DCDP can reach up to 99.8%,with a yield of over 92.5%,which validates the overall feasibility of this process in industrial application.The optimal design and operation conditions are obtained through conducting sensitivity analysis on main design parameters and operation conditions.
