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.
Claims33
A method of devolatilizing recycled carbon black comprising
- introducing said recycled carbon black into a reactor,
- mechanically deagglomerating said carbon black in said reactor,
- devolatilizing said carbon black in said reactor,
- during said devolatilizing of said deagglomerated carbon black subjecting said carbon black to air flow which results in the oxygen in said air reacting with organics on said carbon to evolve heat in order to to establish a high temperature zone in said reactor and thereby increase the temperature at which said devolatilizing is effected, and
- employing said method on recycled carbon black which has been obtained by pyrolysis of vehicle tires in a pyrolysis reactor.
