FIELD: chemistry.
SUBSTANCE: invention relates to recovery of hydrocracking catalyst with suspended layer, which includes: separation (120) of exhaust flow (100) from hydrocracking zone (35) with suspended layer on first part (125), including solvent and clarified resin, and second part (130) including resin and catalyst; contacting (140) of second part (130) with acid (145) for leaching of catalyst from resin for producing aqueous solution (170) and residue (165) resin; and contacting (200) aqueous solution (170) with anion (205) to produce insoluble salt (225) and second aqueous solution (220), where insoluble salt (225) is catalyst.
EFFECT: technical result consists in improved method of regenerating hydrocracking catalyst with suspended layer.
