摘　　要：由于我国轻烃资源缺乏,而石脑油资源相对丰富,考虑将其掺入石脑油进行共裂解。在实验室裂解装置上对油田轻烃、拔头油的分组裂解以及与石脑油共裂解的产物收率变化进行了研究,得出油田轻烃、拔头油的分组裂解优于与石脑油共裂解,因此探讨了拔头油与油田轻烃共裂解的可行性,提出在原料短缺的情况下,可根据"性质相近"的原则进行共裂解,即可将油田轻烃与拔头油掺混进行共裂解。同时在工业裂解炉上进行了拔头油与石脑油共裂解标定试验,得出的结论与实验室结论一致。Due to the lack of light hydrocarbon resources but relative abundance in naphtha resources in China, the light hydrocarbons are co-pyrolyzed with naphtha. The products yield change in pyrolysis of natural gas liquid （ NGL）, topped oil and co-pyrolysis with naphtha in a bench-scale pyrolysis apparatus, are studied. The results show that, the pyrolysis of NGL and topped oil pyrolysis alone are superior to that co-pyrolyzed with naphtha. The feasibility of the co- pyrolysis of topped oil and NGL is investigated. According to ＂similar nature＂ principle of co-pyrolysis, the co-pyrolysis of the mixture of NGL and topped oil is proposed in case of shortage of raw materials. At the same time, a series of copyrolysis tests of naphtha and topped oil are carried out in the industrial pyrolysis furnace. The results are consistent with the laboratory conclusion.
