Starting materials for carbon black produced from catalytically cracked gasoils and containing a small amount of sulfur

1. It has been shown, that, in principle, high-quality starting material for carbon black manufacture can be produced from an appropriate mixture of heavy and polymeric gasoils produced in various types of catalytic cracking units, and from the residue left after distillation of the 270°C fraction from the appropriate mixture of light and heavy gasoils produced in units with a fluid catalyst bed. 2. Extracts from the starting materials mentioned meet all requirements imposed on a starting material for the production of active carbon blacks.
