Optimization of char for NO{sub x} removal. Semiannual report, June 30--December 31, 1996

PDF Version Also Available for Download.

Description

The overall goal of this program is to develop a coal char or carbon capable of selectively removing NOx species from combustion exhaust streams (e.g., exhaust from coal burning power plants) containing both oxygen and NOx. Inexpensive methods to achieve NOx abatement from such streams is presently a major environmental concern. Both fundamental studies of carbon/coal char surface chemistry and tests of different materials under realistic conditions are underway. Work performed for this study demonstrates that the identity of the treatment gas strongly impacts the surface chemistry of activated carbon. Carbon treated in an inert gas will have dangling carbons ... continued below

Description

The overall goal of this program is to develop a coal char or carbon capable of selectively removing NOx species from combustion exhaust streams (e.g., exhaust from coal burning power plants) containing both oxygen and NOx. Inexpensive methods to achieve NOx abatement from such streams is presently a major environmental concern. Both fundamental studies of carbon/coal char surface chemistry and tests of different materials under realistic conditions are underway. Work performed for this study demonstrates that the identity of the treatment gas strongly impacts the surface chemistry of activated carbon. Carbon treated in an inert gas will have dangling carbons on the surface which strongly react with oxygen, and NO, at 300 K. In contrast, hydrogen treated activated carbon will adsorb very little NO at 300 K, but will adsorb significant amounts of NO. The relative selectivity of hydrogen treated carbons toward NO adsorption makes this material a candidate for removal of NO from the exhaust of lean burn combustors.
