FIELD: chemistry.
SUBSTANCE: invention relates to field of catalysis. Described is method of regeneration of catalyst, which contains, at least, one VIII group metal and, at least, one VIB group metal, applied on carrier from heat-resistant oxide, which includes, at least, one first stage of thermal processing of catalyst in presence of oxygen at temperature in the range from 350°C to 550°C, at least, one second stage of sedimentation on the surface of catalyst of one additive of formula : in which groups R1 and R2, identical or different, represent hydrogen atom or hydrocarbon group, linear or branched, saturated or unsaturated, which contains from 1 to 8 atoms of carbon, does not contain aromatic cycle (cycles) and, possibly, contains one or several heteroatoms, selected from atoms of oxygen nitrogen or sulfur.
EFFECT: increase of efficiency.
