METHOD OF REGENERATING SPENT PALLADIUM-CONTAINING CATALYST FOR HYDROGENATION OF PLANT OIL AND FAT

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to processes of generating catalysts for hydrogenation of plant oil and fat. The invention describes a method of regenerating a spent palladium-containing catalyst for hydrogenating plant oil and fat through treatment with sodium hydroxide solution and washing with a condensate, where the catalyst is pre-washed with steam condensate until there are no traces of fat while simultaneously bubbling with hydrogen. Treatment is carried out with 10% solution of sodium hydroxide while blowing with hydrogen at the same time. Washing is carried out with steam condensate until there are completely no traces of alkali and soap and drying is carried out in a hydrogen stream at 145-150C for 8-9 hours. ^ EFFECT: attaining high degree of purification and regeneration of the catalyst. ^ 2 ex
