FIELD: organic chemistry.
SUBSTANCE: invention refers to granular carbon black production process. Produced granular carbon black contains mainly large-spherical granules and can be applied as intensifying extender of elastomers, as well as source material for sorbents and catalyst carriers. Method of carbon black granules production implies consecutive mixing of carbon black flow moving horizontally and rotating with line speed 5-12 m/s and solution of various concentration of bonding additive - molasses - in two zones until granules are formed. Then granules are dried. Molasses amount placed into first zone is 77-80% of required granules amount, the rest of molasses solution 20-23% is introduces to second zone. Invention provides granules production of 3-8 mm.
EFFECT: production of large-spherical carbon black granules.
