优化催化重整反应进料提高产品辛烷值与降低苯含量

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

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C_(5)/C_(6)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。

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 C_(5)/C_(6) 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.
