The ex-situ regeneration of KF-848 hydrotreating catalyst was conducted in Jiangsu Ke-chuang Petrochemical Co. Ltd. and commercial application of the regenerated catalyst in refinery of Li-aoyang Petrochemical Company,PetroChina was introduced. The performance of the catalyst in pilot plant and in industrial unit shows that the regenerated catalyst has a high activity of hydrodesulfuriza-tion,hydrodenitrogenation and aromatics hydrogenation. The activity of the regenerated catalyst rea-ches above 95% of fresh catalyst. It is proved that ex-situ regeneration technology is effective and suc-cessful. Compared with the performance of fresh KF-848 and the catalyst before shutdown,the average temperature of the reactor using the regenerated catalyst is lower by 7-10 ℃;the pressure drop is im-proved. The N content of the product is less than 10 "g?g.
