摘要: 为了更好地适应市场变化,降低全厂柴汽比、多产高辛烷值汽油,中国石油庆阳石化公司采用中国石油石油化工研究院开发的多产高辛烷值汽油并降低柴汽比的柴油催化转化工艺技术(DCP-Ⅰ),通过对重油催化裂化装置现有工艺流程进行简单改造,在二段提升管下部喷嘴处回炼催化裂化柴油。工业应用结果表明:装置回炼催化裂化柴油后,柴汽产率比降低了0.09,稳定汽油中烯烃体积分数降低了0.5百分点,研究法辛烷值增加了0.4,催化裂化柴油密度随着回炼柴油比例的增加略有增加,柴油中饱和烃含量略有下降,芳烃含量略有增加,液化气中丙烯含量略有增加。

Abstract: PetroChina Qingyang Petrochemical Company adopts the diesel catalytic conversion technology (DCP-I) developed by the PetroChina Petrochemical Research Institute o to produce more high-octane gasoline and to reduce the diesel-gasoline ratio. Through the transformation of the existing process flow of the catalytic cracking unit, the FCC diesel was reprocessed at the lower nozzle of the second riser. The commercial application results of DCP-I technology show that after recycling catalytic diesel, the diesel-gasoline ratio of the unit is reduced by 0.09, the olefin content in stabilized gasoline is reduced by 0.5 percentage point, and the octane number is increased by 0.4.

Key words: FCC diesel, diesel-gasoline ratio, refining, high-octane gasoline
