FIELD: chemistry.
SUBSTANCE: invention relates to a method for regenerating a deactivated hydrotreating catalyst for petroleum products by burning coke in a two-loop regeneration reactor at 500-600°C, followed by impregnation with solutions of several acids with heat treatments, including drying and calcination. Intermediate heat treatment is carried out at a temperature of 100-200°C, and the final heat treatment, including drying and calcination, is carried out respectively at a temperature of 100-200°C and 400-650°C for 1-24 hours.
EFFECT: production of a regenerated activated hydrotreating catalyst with a reduced activity of more than 98 percent.
