国内裂解C5产业链出现瓶颈,转型升级迫在眉睫。裂解C5是蒸汽裂解制乙烯装置的副产物,一般为乙烯产量的10%~20%。其组分较为复杂,其中含量较多的为异戊二烯、环戊二烯和间戊二烯,三者占C5馏分的40%~55%。由于裂解C5深加工产业链涉及面较宽,近几年发展迅速。但随着乙烯产能不断扩大,原材料裂解C5供应不断加强,同时下游产业升级较为缓慢,技术瓶颈迟迟未有突破,低端供应趋于饱和。在双重压力下,我国裂解C5产业链进入转
C5 cracked the domestic industrial chain bottlenecks, transformation and upgrading imminent. Cracking C5 is a by-product of steam cracking ethylene plant, typically 10% to 20% of ethylene production. Its components are more complex, of which isoprene, cyclopentadiene and piperylene, the three accounted for 40% to 55% of the C5 fraction. As cracking C5 deep processing industry chain covers a wide area, rapid development in recent years. However, with the continuous expansion of ethylene production capacity, raw material cracking C5 supply continues to strengthen, while the downstream industry to upgrade more slowly, technical bottlenecks have yet to break through, low-end supply tends to saturation. Under the dual pressures, China’s C5 industry chain cracking turn
