摘　　要：随着国内乙烯产能规模快速增长和产业结构不断调整,石脑油裂解制乙烯副产的C_(5)、C_(9)资源量也相应大幅增长,2023年国内裂解C_(5)、C_(9)产能已分别达到409.4万t/a和316.5万t/a,历史5年年均增长率约为10.9%和8.8%。高速增长的资源量使提升C_(5)、C_(9)综合利用价值成为越来越多企业的关注点,下游深加工企业对裂解资源的利用方式由生产传统的资源导向型产品向应用导向型产品转变;上游裂解原料生产企业也开始思考向下游高附加值合成材料领域延伸。With the rapid expansion of China's ethylene capacity and the continuous adjustment of China's industrial pattern,the amount of C_(5)and C_(9)resources produced as a by-product of naphtha cracking for ethylene production has also increased substantially.In 2023,China's capacities of cracking C_(5)and C_(9)reach 4.094 million tons per year and 3.165 million tons per year,respectively,with historical five-year average annual growth rate of about 10.9%and 8.8%.The rapid growth of cracking C_(5)and C_(9)resources has made them increasingly important for more and more companies to enhance the comprehensive utilization value of C_(5)and C_(9),and downstream deep processing enterprises are shifting from producing traditional resource-oriented products to application-oriented products.Upstream ethylene feedstocks production enterprises are also beginning to consider extending to the high-value synthetic materials downstream.
