Nippon Shokubai Co. Ltd has developed a catalyst that can decompose and remove 99 per cent of the dioxin in the exhaust gas from municipal refuse incineration furnaces. The new honeycomb catalyst is manufactured with several types of metal oxides. It is installed in optional position along the exhaust gas route of incineration furnaces, and the dioxin in the gas undergoes chemical reaction on the catalyst, by which the dioxin is decomposed into hydrochloric acid and carbon dioxide. By injecting ammonia gas into the exhaust gas, nitrogen oxides (NOx) can be removed at the same time.
