Abstract
A method for controlling volatiles in recycled carbon black, such as from pyrolysis of tires, includes deagglomerating the recycled carbon black to substantially reduce the carbon black particle size and impinging an air current on the carbon black particles, preferably in a countercurrent direction, to increase the processing temperature and thereby enhance the release of volatiles. Associated apparatus is disclosed.
