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 interval from 350°C to 550°C, at least, one second stage of sedimentation onto the surface of catalyst of one or several additives of formula: in which Ris hydrogen atom; Ris hydrocarbonate bivalent group, linear or branched, saturated or unsaturated, which contains from 1 to 6 atoms of carbon, and, possibly, possibly, substituted with one or several groups of -OH, -OR, -NH, -NHR, -NRR', where R and R' stand for alkyl groups, which contain from 1 to 4 carbon atoms and, preferably, 1 or 2 carbon atoms; Ris hydrocarbon group, linear or branched, saturated or unsaturated, which contains from 1 to 4 carbon atoms.EFFECT: increase of catalyst activity.14 cl, 4 tbl, 2 ex |
