The process of the production of carbon black

The individual primary particles connect each other and create three-dimensional formations called aggregates. The comprehensiveness of their geometric assortment contributes to the character called structure. The chemical reaction is finished by spraying of water into a rear part of reactor.

The created particles are carried away in a stream of hot reaction gas to the next cooling and gas separation in sleeve filters. The so called non-reinforced carbon black is further transported to the pelletizing process in order to improve their transportation properties. The basic link of production of retort carbon black is the reactor with the fire resistant brickwork lining. The carbon black is produced by the the chemical reaction during which imperfect combustion occurs.

CS CABOT uses retort process for the production of carbon black. The raw materials used in the process are heavy hydro-carbons, being obtained during distillation of oil, production of ethylene and by the distillation of coal tar. 

A hot oil is injected into the warmed up reactor. A process of burning is regulated and stopped before completing so that only a small part of the oil will burn for the purpose of maintaining of the reactive temperature, (which moves in range from 1350 to 1800 °C) and the rest will spread during the rise of carbon black.
