METHOD OF PROCESSING DEPLETED VANADIUM CATALYST OF SULFURIC ACID PRODUCTION

FIELD: chemical technology. SUBSTANCE: processing is carried out by treatment of catalyst with alkaline solution (concentration is 30-100 g/l) at 30-100 C at separation of V-containing liquid from slime. Before extraction 0.35-3% HPO(as POof depleted catalyst mass) is added to V-containing liquid fo...
