摘要
随着环保法规的日益严格,降低催化裂化汽油烯烃含量具有重要的现实意义。基于负氢离子转移反应对双分子反应影响机理,提出选择性氢转移反应调控催化裂化汽油烯烃的新理念,发现富含芳香基环烷烃和多环环烷烃组分可以作为负氢离子释放剂,用于调控汽油烯烃含量并抑制焦炭生成。通过反应模式调控和引入负氢离子释放剂等技术创新,成功开发生产超低烯烃汽油的催化裂化技术(ULO)。工业应用结果表明,采用ULO技术可一步法生产烯烃体积分数小于10%的稳定汽油,维持较高的汽油辛烷值和较低的焦炭选择性,并实现了轻循环油的高价值转化。
With the increasingly stringent environmental regulations,reducing the olefin content of FCC gasoline has practical significance.Based on the mechanism of the hydride ion transfer reaction on the bimolecular reaction,a new concept of selective hydrogen transfer reaction is proposed to regulate and control gasoline olefins.It is found that the components rich in naphthenic aromatics and polycyclic alkanes can be used as hydride ion release agents to control gasoline olefins and inhibit the formation of coke.Through technological innovations such as the regulation of reaction modes,and the introduction of hydride ion release agents,the catalytic cracking technology for producing ultra-low olefin gasoline(ULO)has been successfully developed.The industrial application results show that ULO technology can be used to produce stable gasoline with a volume fraction of olefin less than 10%,maintaining gasoline octane number and coke selectivity,to realize the high-value conversion of LCO.
