Abstract

More than 18 million tons of nitrogen oxide (NO and NO2) are emitted into the air over the United States each year. These oxides contribute to the formation of acid rain and street level ozone, and are most concentrated in areas of industrial and commercial activity. The response of the Environmental Protection Agency to the problem has been to legislate anti-pollution laws and regulations which will be enforced in increasingly strict stages beginning in 1997. Existing NOx abatement technologies do not meet the long range NOx abatement needs of the processing industries and utilities.

Char, a heat treated and volatile form of coal, can effectively adsorb NOx from waste gas. Microwave energy, when properly applied, can convert the NOx and carbon via reduction to nitrogen and carbon dioxide. The basic principles of this technology are taught as well as some of the pertinent development aspects currently under investigation.
