Abstract
1355848 Treating exhaust gases ZEUNASTRKER K G 10 Sept 1971 [12 Sept 1970] 42350/71 Heading F1B I. C. engine exhaust gas purifying process consists of the steps of oxidizing the hydrocarbons and carbon monoxide in the exhaust gas in an afterburner, the oxidation of the carbon monoxide being incomplete, so that the proportion remaining is ten times greater than the proportion of nitric oxides in the exhaust gas, and then passing the gas over a catalyst which promotes a reaction between the carbon monoxide and nitric oxides resulting in the formation of carbon dioxide and nitrogen. Fresh air is injected into the exhaust manifold upstream of the afterburner, the quantity being sufficient to allow for complete combustion of the hydrocarbons but to result in the stoichiometrical amount of carbon monoxide to be present to react with the nitric oxides. It is permissible for a small amount of hydrocarbons and a slight excess of carbon monoxide to reach the chamber containing the catalyst, which may also contain 0À5-0À8% oxygen by volume. The catalyst is preferably a granular metal oxide and may be contained in a separate chamber or may be used to line parts of the afterburner chamber which are subject to particularly severe wear. In an example the exhaust gas initially contained, by volume, 4% CO, 0À06% CH and 0À12% NO. After treatment in the afterburner the gas contained 1À5% CO, 0À003% CH and the original quantity of NO, which was subsequently reacted with the CO, the gas ultimately containing 0À3% CO.
