Abstract

Decreasing the dioxin generated from combustion furnaces in waste incinerators and in other facilities that burn waste is a very important goal for society. Various technologies for decreasing dioxin in waste incinerators were investigated. However, while dioxins are collected by dust collectors, they are not removed from the dust or decomposed, so a fundamental decrease in dioxins is not achieved.<br>Consequently, we examined a basic technology that can resolve this problem by using low-cost ore with Mn content. The oxidation decomposition behavior of monochlorobenzene (MCB), which is known as a compound that is a precursor of dioxin, was investigated. This was evaluated using the burned product of the Mn ore, which mainly contains Mn₂O₃. In this condition, the burned product of the Mn oresuggests that it could have a decomposition effect with MCB for a long time. Moreover, reaction analysis results suggest it should not only have a role as an oxidation agent but also have an effect as a catalyst.
