Carbon black is produced from a combustion – pyrolytic process. This process typically converts petroleum-based feedstock oil into carbon black by injecting oil into a reactor, which “cracks” the oil at temperatures in excess of 1000°C.
The reaction process, occurring in milliseconds, ends with a quenching step at the reactor’s outlet.
A carbon black aerosol stream emerges from the reactor and then passes through a series of filters to separate the carbon black from the combustion gases. Then carbon black is collected as powder or granular product and packaged for delivery to customers in every part of the world. Carbon black colloidal and performance properties are a function of a number of process factors plant adjusts these properties to produce high quality ASTM grades and specialty grades to meet the specific end-market requirements where carbon black is consumed.
