摘　　要：通过自生成热裂解反应网络模型对单组分碳四烯烃的裂解反应进行模拟。模拟结果表明,1-丁烯和2-丁烯的裂解产物中丁二烯收率高于常规裂解原料。利用模拟裂解实验装置,进行富烯烃碳四物料的裂解实验,验证了模拟计算结果;并将富烯烃碳四物料与石脑油原料进行混合裂解,产物中丁二烯收率有所提高。进一步在工业裂解炉上进行了富烯烃碳四物料与石脑油混合裂解试验。工业试验结果表明,裂解产品中丁二烯收率明显提高,同时三烯(乙烯、丙烯和丁二烯)收率有所提高,达到了增产丁二烯的目的。How to increase the production of butadiene in ethylene plant was studied and the pyrolysis of C4 olefins was simulated by means of a self-generated reaction model. It was indicated that the butadiene yields in the pyrolysis of 1-butene and 2-butene were both higher than the yield in the pyrolysis of conventional feedstock. The olefin-rich mixed C4 pyrolysis test was carried out in a simulation test device and the simulated calculation results were verified. In an ethylene plant, the test was carried out with naphtha and olefin-rich mixed C4 as the feedstock. The test results showed that the butadiene yield increased significantly and the purpose of increasing butadiene product was achieved.
