Gasification of waste‐contaminated soil by the chem char process

Abstract

Reverse‐burn gasification (RBG, the ChemChar Process) has been applied to the treatment of soil contaminated with hydrocarbons, poly‐chlorinated biphenyls (PCBs) and thorium. Overall destruction of the PCBs in excess of 99.9999% (six nines) was achieved. No undesirable dibenzo dioxins or furans were produced, and metals and acid gases are retained in the char residue matrix. An overall hazardous waste treatment system based on gasification is described.
