Description

This invention concerns a method of complete combustion of unburnt products such as soot formed upon combustion of ion exchange resin. Ion exchange resins are burnt under the supply of air at 650 - 850degC. Combustion is taken place on a free board under the pressure of a flowing catalyst of fine alumina particles. The ion exchange resins do not burn completely but produce soots and unburnt organic products. Then, a catalyst comprising a copper net and a stainless steel net is disposed on the free board, so that the unburnt products undergo complete combustion in contact with the catalyst. Thus, complete combustion of the ion exchange resins is possible to attain volume-reduction thereof. (K.M.)
