The dioxin volatilization and decomposition process was developed to remove dioxin from fly ash in MSW (Municipal Solid Waste) incinerators. In this process, dioxin adsorbed on the surface of fly ash is volatilized to the gas phase and then decomposed by catalytic or high temperature treatment. This process significantly suppresses dioxin reformation by de-novo synthesis in the treated fly ash because of the simultaneous removal of other organic compounds that may be sources for dioxin reformation.
