摘要：利用中国石化长岭分公司1号催化裂化装置实测数据,采用集总理论研究FDFCC工艺汽油提升管内的催化反应行为。根据集总原则,将汽油提升管内反应系统的原料和产品按馏程及烃族组成划分为九个集总组分,通过合理简化反应网络,建立九集总反应动力学模型,并求取25组反应动力学参数,并对不同性质原料在不同操作条件下的产品分布进行验证。结果表明,该模型能较好预测汽油产品组成及液化气中高附加值的丙烯产率。
Based on the data collected from the 1# FCC Unit of SINOPEC Changling Company, the catalytic reaction behavior of naphtha in gasoline riser of FDFCC process is studied. According to the principle of lumped theory, the feed and product in gasoline riser based on distillation range and hydrocarbon group composition are divided into 9 lumps including gasoline saturated hydrocarbons（GS）, gasoline olefins（GO） ,gasoline aromatics（GA）,diesel oil（DI）,LPG alkane（LP） ,LPG butene（LO4）,LPG propylene（LO3）, dry Gas （DR）and coke （CK）. A 9 lumps kinetic model is established by reasonably simplifying the reaction network and 25 kinetic parameters are fitted. The model is validated by the product distributions of various feeds under various operating conditions. The results show that gasoline compositions and propylene yield in LPG can be predicted by said model quite well.
