优化催化重整反应进料提高产品辛烷值与降低苯含量

某炼油厂通过采用中国石化石油化工科学研究院(简称石科院)研制的SR-1000半再生重整催化剂，对半再生催化重整装置现有蒸发塔改造，从原料性质方面合理控制和优化，在进入催化重整装置之前切出苯的前身物(包括苯及环己烷),以及采用石科院开发的C₅/C₆异构化组合工艺技术等措施，将稳定汽油的研究法辛烷值(RON)提高至96以上时，能够生产出苯质量分数小于1.0%的汽油调合组分，由此实现停运单苯抽提装置，经济效益和社会效益显著。

IMPROVING OCTANE NUMBER AND REDUCING BENZENE CONTENT OF PRODUCT BY OPTIMIZING CATALYTIC REFORMING FEED

After adopting the SR-1000 semi-regeneration reforming catalyst developed by SINOPEC Research Institute of Petroleum Processing (RIPP), revamping the existing evaporator of the semi-regeneration catalytic reforming unit, reasonable controlling and optimizing the raw material properties, cutting out the precursor of benzene (including benzene and cyclohexane) before catalytic reforming, and using the combined process of isomerization of C₅/C₆ developed by RIPP,the RON of the product was increased to above 96, the blending component of gasoline whose benzene content was less than 1.0% could be produced, and the single benzene extraction unit could be shut down. The economic and social benefits were remarkable.
