Studies of ChemChar cocurrent flow gasification of hazardous wastes using radiolabeled compounds

This paper describes investigations of the ChemChar thermal process using radiolabeled compounds. The process uses triple reverse-burn (TRB) char as the waste carrier. Production weight/volume loss and adsorption characteristics of TRB char were investigated. Batch mode laboratory scale gasification systems were developed to study the fate of radiolabeled organic compounds at low and high loadings. The following conclusions were drawn from experimental results: (1) TRB char sorbs pollutants, independent of their being in the aqueous phase or gase phase, (2) TRB char incorporates carbon during cocurrent gasification of hydrocarbons and organohalides, (3) none of the compounds tested (benzoic acid; chlorobenzene; 1,4-dichlorobenzene; hexachlorobenzene; 3,3`,4,4`-tetrachlorobiphenyl; and dibenzofuran) produced oxygenated organic byproducts during cocurrent gasification, (4) strong reductive destruction mechanisms are predominant during cocurrent gasification in a batch mode reactor, and (5) none of the chlorinated compounds tested formed byproducts with a higher number of chlorine atoms than the parent compounds.
