Abstract: Based on the historical operation data，the performance of PS Ⅵ reforming catalyst was summarized.The analysis indicated that the PS Ⅵ reforming catalyst has good wear resistance，hydrothermal stability and chlorine holding capacity.The initial activity of the catalyst is high along with a long stable service life and good catalyst strength.Keeping moderate higher Cl content on the catalyst is helpful to get better product distribution.The sulfur，nitrogen and metal impurities in feed affect the performance of the catalyst and higher sulfur in feed has worse effect on the carbon deposition，thus the coke burning operation conditions in the regeneration sector must be adjusted； The nitrogen in the reforming feed reacts with chlorine to produce ammonium salt，which causes the blockage and corrosion in the separation equipment and the pipeline of the reforming device.

Key words: catalyst, performance, field application, continuous reforming, water-chlorine balance
