摘要
在连续流化催化裂化装置上,对柴油重馏分选择性裂化多产高辛烷值汽油工艺(MIP-LTG)进行中型试验研究。结果表明:将反应温度控制在合理的范围内可以在高转化率、高丙烯产率的情况下得到较高的汽油产率和性质较理想的汽油产品;提高剂油比可以提高转化率,增加液化气和汽油产率,提高汽油辛烷值,但会提高干气和焦炭产率;原料性质对产物分布和产品性质有着至关重要的影响,原料中芳烃含量越高,尤其是单环芳烃含量越高,汽油产品中芳烃含量越高,汽油辛烷值越高。
The investigation of a MIP-LTG process for enhancing high octane gasoline production by cracking heavy diesel fraction was conducted in a continuous catalytic cracking unit. The test results show that a high yield of good quality gasoline can be obtained at high conversion and propylene yield in appropriate reaction temperature range. By increasing catalyst to oil ratio,the conversion,liquefied gas yield,gasoline yield and octane number are all increased,while more dry gas and coke is observed as well. The properties of feed have a critical influence on the product distribution and properties. The higher aromatic content,in particular,the higher monocyclic aromatic content in the feed,the higher content of aromatics in the gasoline product,and the higher gasoline octane.
