【摘要】：采用基于结构导向集总的催化裂化MIP工艺反应动力学模型对中国石化某分公司Ⅰ套催化裂化MIP装置的操作条件进行优化,考察了催化裂化产物的平均相对分子质量、汽油收率及汽油中典型组分的含量沿提升管高度的变化情况。实验结果表明,一反区平均相对分子质量随提升管高度的增加显著下降,当一反区出口温度为515℃,剂油质量比为6.0时,一反区平均相对分子质量由712下降为196,表明裂化反应主要发生在一反区;模型优化结果表明,在一反区出口温度500~510℃,剂油质量比6.5~7.0的条件下,汽油收率高于50%,汽油中烯烃含量低于24%(φ),满足国Ⅴ指标的要求。为工业催化裂化MIP装置的生产提供理论指导。
[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，
