Destruction of carbon tetrachloride was found to be 94±1 at 300℃for a single pass through activated carbon. Product analysis indicates that conversion was limited to low molecular weight gases. No formation of toxic halogenated organiccompounds, such as phosgene, dioxins, dibenzo-p-dioxins, or dibenzofurans, were observed in the degradation process. Isotopic labeling experiments suggest that the activated carbon acts as a reagent and that carbon from the activated carbon may initiatethe breaking of the carbon-chlorine bond in carbon tetrachloride.
