摘要

从催化裂化反应机理出发,提出了两个反应区的概念,设计了具有两个反应区的串联提升管反应器并形成相应的工程技术,在此基础上进行了中小型探索试验和工业试验。1.4 Mt/a多产异构烷烃的催化裂化装置试验标定结果表明:与现有的催化裂化工艺相比,该工艺不仅优化了产物分布,干气和油浆产率分别下降了0.41%和0.99%,液体收率增加了1.17%,而且所生产的汽油烯烃含量下降约14.1%,异构烷烃增加约为12.9%,硫的质量分数ω(s)下降26.5%,诱导期增加,汽油的RON下降而MON增加,总的抗爆指数略有下降。

Abstract

A concept of two different reaction zones was proposed based on the FCC reaction mechanism. The concept was used to design a novel reactor with corresponding engineering measures. Experiments were conducted on the newly developed reaction system. The test run results of the 1.4 Mt/a MIP commercial unit showed that mass yield of dry gas was reduced by 0.41 % and mass yield of slurry was reduced by 0.99% , while mass yield of light ends was increased by 1.17%. The volume fraction of olefin in the cracked naphtha dropped by 14.1% while the volume fraction of isoparaffin increased by 12.9% and the mass fraction of sulfur was reduced by 26.5% with maintaining the octane rating index unchanged and a significant extension of the induction period compared with the conventional FCC process.
