| 摘 要： | 从分析LCO化学组成入手，提出了LCO加氢与催化裂化组合生产高辛烷值汽油或轻质芳烃的技术——LTAG技术。在该技术中，加氢单元需进行选择性加氢控制，即双环芳烃选择性加氢饱和生成四氢萘型单环芳烃；催化单元要实现选择性裂化，即选择性强化四氢萘型单环芳烃开环裂化反应，抑制氢转移反应。工业应用结果表明，LTAG技术中加氢LCO转化率大于70%，汽油选择性接近80%，汽油辛烷值提高。

| Abstract: | Based on hydrocarbon type composition of LCO, a technical route integrating hydrotreating with catalytic cracking process LTAG was proposed and two key issues were studied in detail for inferior LCO to produce high RON FCC naphtha or light aromatics. In LTAG technology the di aromatics in LCO must be selectively hydrotreated in hydrotreating unit to mono aromatics with tetralin structure, while ring opening reactions must be strengthened and hydrogen transfer reactions must be inhabited in the followed FCC process for the new generated mono aromatics. The commercial results of LTAG showed that H LCO conversion exceeded more than 70%, gasoline selectivity was almost 80%, and gasoline RON was improved. |
