SYSTEM UND VERFAHREN ZUM REGENERIEREN ODER HERSTELLEN VON AKTIVKOHLE

摘要

This invention relates to a system for regenerating and manufacturing activated carbon wherein the exhaust gases and vapors from the upper portion of a multiple hearth furnace are passed to a gas cooling apparatus such as a quencher or scrubber, the clean gases from which system are exhausted and from which a slip stream of water saturated gases are conducted to a lower hearth portion of the furnace for reaction with the carbon in the furnace.
