DETAILED MECHANISM OF DIBENZOFURAN OXIDATION

Abstract : A number of high temperature industrial processes such as municipal waste incineration, recycling of scrap to produce steel in electric arc furnaces, sintering of iron ore, etc , lead to the formation of "dioxins" (PolyChlorinated Dibenzo-p-Dioxins and PolyChlorinated DibenzoFurans, or "PCDD/Fs") in trace amounts. Their toxicity needs to keep their formation as low as possible by using all the available techniques (process modification, post-treatment,...). To limit the emissions of dioxins (PCDD/Fs), there are three possibilities which in fact are complementary : - to limit their formation by choosing "clean" raw materials, by modifying the industrial process, the conditions of the reaction, - to destroy the dioxins after their formation, - to trap the dioxins in the flue gas by an adsorption process. An efficient way of lowering the emissions of PCDD/Fs is an optimisation of the postcombustion process to keep the level of organics emitted as low as possible.
