MTP副产汽油性质及其综合利用方案

Discussion on Properties and Comprehensive Utilization Plan of MTP By-Product Gasoline

MTP副产汽油与石油路线汽油相比具有低硫低氮、辛烷值高的特点,但诱导期短、胶质含量高,组成随着MTP催化剂运行周期变化而变化,且各组分较为分散,综合利用难度大,催化裂解和芳构化均存在预处理流程长,不经济的问题。

Compared with petroleum gasoline,MTP by-product gasoline has the characteristics of low sulfur,low nitrogen and high octane number,but the induction period is short and the content of colloid is high.The composition changes with the operating cycle of MTP catalyst,and the composition is unstable.Moreover,the components are relatively dispersed,and the comprehensive utilization is difficult.At present,both the catalytic cracking and the aromatization have long pretreatment processes and are not economical.
