摘　　要：FDFCC工艺是降低催化汽油烯烃含量的有效技术。论述了该工艺的技术特点、流程设计和工业应用情况。工业应用结果表明,该工艺可使烯烃体积分数降低30个百分点左右,硫含量下降20%左右,改质汽油诱导期增加,MON和RON略有增加,并且苯含量基本维持不变,芳烃含量远远小于规定指标40%。The technical features,process design and commercial application of FDFCC process for cracked naphtha olefin reduction were described.The results of application showed that the olefin content in cracked naphtha decreased about 30%,sulfur content decreased about 20%,the induction period increased,MON and RON increased slightly with benzene content nearly unchanged,and aromatics content was 40% below the specification.

关 键 词：FDFCC工艺 降低汽油烯烃 工业实施
