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.
