Alumina Catalysts for Reduction of NOx from Methanol Fueled Diesel Engine 960137

NOx selective reducing catalysts are expected to be used for lean-burn gasoline engines and diesel engines as an effective NOx reduction measure. We are interested in the combination of methanol, as a reducing agent, and alumina catalyst, and have considered the NOx reduction method using effectively much unburned methanol. In this report, in order to investigate the effect of NOx reduction by the alumina catalyst, the experiment was carried out by feeding the actual exhaust gas from the methanol engine into the alumina catalyst. As a result, it was confirmed that, without addition of any other reducing agents into the exhaust gas, the alumina catalyst has activity to reduce NOx.
