Abstract
There is provided a system for reactivating wet, spent carbon including a drying device to heat the carbon to drive moisture from the carbon as steam. A multiple-hearth furnace receives the carbon from the drying device, and the carbon is baked and reactivated therein. Reactivation is accomplished in the presence of steam, at least part of which is the steam which had been driven from the wet, spent carbon.
