Diesel engines, both stationary and mobile, are major sources of air pollution. Pollutants of concern are solid and liquid particulates, nitrogen oxides (NOx), toxic hydrocarbon gases, and, in some cases, sulfur dioxide (SO{sub 2}). Approaches considered in the past to reduce these pollutants have included modifying the engine design, modifying the fuel composition, recirculating the exhaust gases, and installing a device or system on the exhaust gas stream to remove or modify the undesirable constituents. Of particular concern to the U.S. Air Force are the high levels of NOx that are present in their diesel engine exhaust gases. Sorbent Technologies Corporation (Sorbtech) engineers, during the past two years, have been examining and developing ways to remove NOx from these exhaust gases. The principal NOx species in diesel engine exhaust gases is nitric oxide (NO). Typical NO levels range from 100 to 1200 ppm. Higher NO levels generally occur with higher engine loads that result in higher engine temperatures. This paper describes the use of activated carbon for pollution control of NO.
