Zusammenfassung:	FIELD: petrochemical processes. SUBSTANCE: in a method where hydrocarbon stock is heated and then fed into carbon black-production apparatus from which resulting carbon black is withdrawn after cooling, hydrocarbon stock is preliminary separated into narrow fractions with boiling limits separated by 10-40 C, preferably 10-15 C, which fractions are fed into reaction apparatus separately. EFFECT: increased fineness of product. 2 cl, 1 tbl
