摘　　要：如何高效加工催化裂化柴油(LCO)中大分子芳烃一直是炼油企业提高经济效益的关键之一。中石化石油化工科学研究院有限公司以大分子芳烃化学反应网络为基础,通过催化材料、工艺技术和反应工程等集成创新,先后开发了中压加氢改质MHUG技术、LCO加氢裂化生产高辛烷值汽油或芳烃的RLG技术。MHUG技术加工LCO、焦化汽柴油等劣质原料,通过芳烃加氢饱和、开环反应得到高十六烷值的清洁车用柴油和高芳烃潜含量的石脑油;RLG技术加工LCO、重芳烃等原料,通过芳烃选择性加氢饱和、选择性开环、断侧链反应得到小分子芳烃(BTX),从而得到高辛烷值汽油调合组分或BTX抽提料。该平台技术的开发与应用为我国柴油质量升级、油转化、降低柴汽比、提高经济效益提供了有力的技术支撑。The efficient processing of typical macromolecular aromatic hydrocarbons in light cycle oil(LCO)has always been one of the keys to improve enterprise economic efficiency.Based on the chemical reaction network of macromolecular aromatics in LCO,through the integrated innovation of catalytic materials,process technology and reaction engineering,SINOPEC Research Institute of Petroleum Processing Co.,Ltd.has successively developed the medium pressure hydro-upgrading technology(MHUG)and LCO hydrocracking to produce gasoline with high octane or aromatics technology(RLG).MHUG technology can process inferior raw materials such as LCO and coking diesel,and the clean vehicle diesel with high cetane number can be obtained through aromatics hydrogenation saturation and ring opening reaction.RLG technology can process LCO and C 9 C 10+heavy aromatics,and the high-octane gasoline blending components or BTX extracts can be obtained through aromatics selective hydrogenation saturation,selective ring opening,and side chain break reaction.The development and application of the platform technology provides strong technical support for LCO upgrading,oil-to-chemicals,reducing the ratio of diesel to gasoline,and improving economic benefits.
