石脑油和轻烃资源裂解方式优选研究

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。

Optimal selection of pyrolysis ways of light hydrocarbon resources and naphtha

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 co-pyrolysis tests of naphtha and topped oil are carried out in the industrial pyrolysis furnace.The results are consistent with the laboratory conclusion.
