ChemChar Process for Carbon Re-Activation
The ChemChar reverse-burn gasification process was evaluated to determine its feasibility for use in the regeneration of spent activated carbon. This non-incinerative, thermochemical gasification process pyrolyzes the sorbed wastes and restores the sorptive capacity of the carbon in one energy-efficient step. The effects of moisture and supplemental fuel addition on regeneration were determined with a laboratory-scale reactor and a flow-through assay method was developed for determining regeneration effectiveness. The process produces good quality regenerated carbon simply and inexpensively with a minimum of carbon loss. Carbons can be regenerated several times and the method is non-polluting.
