Due to the hazardous implications of releasing CFCs into theenvironment, studies on their thermal destruction are necessary. Theuse of incineration to destroy these compounds, while effective, haveproduced polychlorinated dibenzodioxins and polychlorinateddibenzofurans (PCDD/PCDF) while releasing large amounts of corrosiveHCl and HF. The ChemChar gasification process was evaluated for itsability to destroy two CFCs, 1,1,2-trichloro-1,2,2-trifluoroethane(CFC-113) and dichlorodifluormethane (CFC-13). It was found that DREvalues of >99.9998/100 are obtained for the destruction of1,1,2-trichloro-1,1,2-triflurooethane while not producing anyPCDD/PCDF. Additionally, the chloride (as the potassium salt) andfluoride (As carbon-fluoride) that result from the destruction ofboth CFCs are retained in the gasification system. This studyillustrates that the ChemChar gasification process holds significantpromise as an alternative to incineration for the safe and completedestruction of CFCs.
