摘　　要：中国石化安庆分公司(简称安庆分公司)为优化企业产品结构,提高经济效益,采用中国石化石油化工科学研究院研发的催化裂化柴油加氢裂化生产高辛烷值汽油的RLG技术及其专用的加氢精制催化剂和加氢裂化催化剂,新建了一套1.0 Mt a催化裂化柴油加氢转化装置(简称RLG装置)。该装置已平稳运行18个月,装置长周期生产运行及工业技术标定结果表明,RLG装置以100%劣质催化裂化柴油为原料,高辛烷值汽油调合组分收率为45%~60%、RON为90~95、硫质量分数小于2μg g,柴油产品十六烷指数提高12~14个单位、硫质量分数小于5μg g,实现了催化裂化柴油高效转化为高辛烷值汽油,汽油和柴油产品性质好,气体产率低。RLG装置投产后,安庆分公司的柴汽比由1.03下降至0.74,经济效益显著提高。In order to optimize the enterprise product structure and improve the economic efficiency,SINOPEC Anqing Company built a new 1.0 Mt a LCO hydrocracking unit using RLG technology developed by SINOPEC Research Iastitute of Petroleum Processing to produce high octane number gasoline with relative hydrofining catalyst and hydrocracking catalyst.The unit has been operating safely for 18 months under the condition of processing 100%low quality LCO raw materials.The calibration results after long term operation showed that the yield of high octane gasoline component was 45%-60%and RON was 90-95,sulfur mass fraction was less than 2μg g;at the same time,the diesel cetane index was improved by 12-14 units,sulfur fraction score was less than 5μg g,indicating that RLG realized the efficient conversion of FCC LCO into high octane gasoline with good qualities and diesel products and low gas yield.The adoption of RLG technology reduced the ratio of diesel to gasoline from 1.03 to 0.74,and the economic benefit was significantly improved.
