Method for decomposing chlorine-containing organic compound in exhaust gas and catalyst for use in the method

摘要

The invention is to provide a method for decomposing chlorine containing organic compounds contained in an exhaust gas which contained in the exhaust gas with nitrogen dioxide which is contained in the exhaust gas or added from the outside into the exhaust gas at 100 to 450 °C in the presence of a catalyst comprising a titanium oxide, molybdenum oxide, and vanadium oxide, the contents of Ti, Mo, and V in which catalyst being in the range of 99 to 70/0.5 to 15/0.5 to 15. Method for decomposing chlorine containing organic compounds (DXN) contained in an exhaust gas in which method a high decomposition ratio of the DXNs can be obtained even at a low temperature and the effects by SOx can be repressed to a minimum.
