Abstract: A company's 3.1 MMTPY continuous reforming unit adopts domestic ultra-low pressure continuous reforming (SLCR) technology with independent intellectual property rights, and uses continuous reforming catalyst PS-Ⅵ. It is currently the largest domestic continuous reforming unit. After the large-scale installation, during the thermal assessment stage, the displacement of various equipment and pipeline supports and hangers in the reaction and regeneration system is normal and consistent with the design data. After the unit is put into operation, the trend of thermal displacement in the reaction and regeneration system is consistent with the results of the thermal assessment. The performance assessment results of the unit show that, in the case where the aromatic potential content of the raw material is 7.49 percentage points lower than the design value, the liquid yield of C+5 of the unit is 88.15%, the pure hydrogen yield is 3.80%, the mass fraction of aromatic hydrocarbons in the depentane oil is 82.84%, and the aromatic hydrocarbon conversion rate is 172%. After half a year of operation, the catalyst dust content is stable from 8 kg/d to 12 kg/d, and all economic indicators are good. The PS-Ⅵ catalyst shows good reaction activity, selectivity, and low wear rate.

摘要： 某公司3.1Mt/a连续重整装置采用具有自主知识产权的国产超低压连续重整（SLCR）技术，选用连续重整催化剂PS-Ⅵ，是目前国产化规模最大的连续重整装置。装置大型化后热态考核阶段，反应-再生系统各设备、管线支吊架位移正常，与设计数据吻合。装置投料开工后，反应-再生系统热位移趋势与热态考核结果一致。装置性能考核结果表明：在原料芳烃潜在含量比设计值低7.49个百分点的情况下，装置C+5液体收率为88.15%，纯氢收率为3.80%，脱戊烷油芳烃的质量分数为82.84%，芳烃转化率为172%。装置运行半年后，催化剂粉尘量稳定在8～12kg/d，各项经济指标参数良好，PS-Ⅵ催化剂表现出良好的反应活性、选择性及较低的磨损率。
