Abstract
Environmental release of carcinogenic polychlorinated dibenzo-dioxins and polychlorinated dibenzo-furan compounds that typically result from combustion of materials containing chlorine or hydrochloric acid-generating components is minimized by preferential sorption of the precursor reactants on sorbents added to exhaust gas at high temperatures containing such precursors prior to conversion of the precursors to carcinogenic compounds normally occurring as the exhaust gas is cooled.
