Composition for use in reducing air contaminants from combustion effluents.

摘要

An effective process is provided for cleanly and safely combusting coal or other carbonaceous material in a manner which enhances the environment by reducing emission of pollutants. In order to reduce nitrogen oxide and sulfur oxide emissions during combustion, combustion is carried out in the presence of one or more additives comprising an alkali metal salt, such as sodium chloride. To further enhance the reaction and removal of sulfur oxides and nitrogen oxides, the additive can include an iron-containing compound, such as iron oxide, and/or a metal oxide, such as manganese oxide.
