摘　　要：根据工业装置运行数据,分析了固定床渣油加氢装置中低碳气体烃发生自由基机理反应的热裂解过程。试验结果表明,正丁烷含量是异丁烷的2.5~4.0倍;在装置运行初期,低碳气体烃约占总进料量的4.67%,随着反应温度的升高,低碳气体烃的含量也会增加,装置运行末期甲烷含量约为初期的2倍。Based on the operation data of industrial unit,the thermal cracking process of low-carbon gas hydrocarbons in fixed bed residue hydrogenation unit was analyzed.The test results show that the content of n-butane is 2.5-4.0 times that of isobutene.Low-carbon gas hydrocarbon is about 4.67%of the feed at the initial stage of operation.As the reaction temperature increases,the content of low-carbon gas hydrocarbons also increases,and the methane content at the end of the plant operation is about 2 times of that at the beginning.
