RAW MATERIALS FOR PRODUCTION OF CARBON BLACK

摘要

FIELD: production of carbon black. SUBSTANCE: raw materials comprise, mas. %: 110-360 C fraction of processing of pyrocondensate of hydrodealkylation of mixture xylene and toluene, 10-22; distillate of thermopolymerization of light pyrolysis resin (its average volume boiling point is 220-238 C), 5-15; product of pyrolysis of hydrocarbons (its average volume boiling point being 260-290 C) and coke residue, the balance. Raw materials comprise 2.1-4.0 % of compounds insoluble in pentane. Iodine number of carbon black is 108-111 g/kg. EFFECT: improved quality of product.
