Abstract: A dioxin preventative includes an adsorbent that sorptively removes dioxin precursors from an exhaust gas stream of an incinerator at a point prior to the exhaust gas stream cooling to below a temperature of 400.degree. C. The dioxin preventative includes a covering agent which coats flyash.

Abstract: Formation of toxic polychlorinated dibenzo-p-dioxins and other chlorinated compounds by catalytic reactions on flyash produced in the process of solid waste incineration is a universal phenomenon. By providing inhibitors which adsorb on the flyash prior to catalytic reaction initiation to suppress catalytic reactions on the flyash, in the postcombustion zone of the incinerator, or by spraying the inhibitors on the solid wastes prior to incineration, has resulted in a decrease in dioxins and other chlorinated compounds on the flyash and in the stack emissions. Introduction of inorganic and organic basic compounds on solid waste or between combustion and precipitation regions of the incinerator also decreases acid gases in the stack emissions.

Abstract: In the conventional incineration of solid waste materials, flyash present in the combustion products gas stream catalyzes the formation of toxic dioxins from chlorinated organic materials. By providing a catalyst poison, such as carbon disulphide, in association with the flyash, typically by spraying onto the solid wastes prior to incineration, the catalytic effect is decreased, resulting in decreased dioxin formation.
