【摘要】：采用基于結構導向集總的催化裂化MIP工藝反應動力學模型對中國石化某分公司Ⅰ套催化裂化MIP裝置的操作條件進行優(yōu)化,考察了催化裂化產物的平均相對分子質量、汽油收率及汽油中典型組分的含量沿提升管高度的變化情況。實驗結果表明,一反區(qū)平均相對分子質量隨提升管高度的增加顯著下降,當一反區(qū)出口溫度為515℃,劑油質量比為6.0時,一反區(qū)平均相對分子質量由712下降為196,表明裂化反應主要發(fā)生在一反區(qū);模型優(yōu)化結果表明,在一反區(qū)出口溫度500~510℃,劑油質量比6.5~7.0的條件下,汽油收率高于50%,汽油中烯烴含量低于24%(φ),滿足國Ⅴ指標的要求。為工業(yè)催化裂化MIP裝置的生產提供理論指導。
[Abstract]:The operation conditions of the first set of FCC MIP units in Sinopec were optimized based on the structural steering aggregate MIP process reaction kinetics model. The average molecular weight of FCC products was investigated. The variation of gasoline yield and the content of typical components along the riser height. The experimental results show that the average molecular weight of the first reaction region decreases significantly with the increase of the riser height. When the outlet temperature of the first reaction zone is 515 鈩，
