Development of Catalyst for Selective Reduction of NOx and Oxidation of CO and Hydrocarbons

Abstract

Presently available technologies for control of engine NOx are not applicable in diesel engines and microns research projects are in progress in both the U.S. and Japan to find a practical method of catalytically reducing NOx in diesel exhaust. This report describes are laboratory scale testing of two possible methods of doing this. Tests were done with gas mixtures which simulated diesel exhaust. Of the two NOx control methods tested, one was found unpromising while the other gave promising results when propane was used as the NOx reducing agent. Since, however, the results with diesel fuel as the reducing agent were not promising, further development did not seem justified. It appears likely than the need to used diesel fuel is the NOx reductant in any practical system will be an issue in the other research projects now ongoing.
