Fundamental study of NOx control in catalytic combustion. Final report, January 1992-December 1994
La1-xSrxCoOe perovskite, doped alumina, and hexaaluminate catalysts have been examined for CH4 oxidation, NO reduction, NO decomposition, and CH4+NO+O2 reactions. Hexaauluminate catalyst is more stable and active for CH4 combustion than perovskite after calcination at high temperatures. A new aqueous coprecipitation method for hexaaluminates was developed. This coprecipitation method is a simple important step forward for the application of CH4 catalytic combustion. Various characterization techniques and steady-state isotopic transient kinetic analysis (SSITKA) have been used to correlate the physico-chemical properties for the catalysts with their catalytic activity for CH4 oxidation and NOx formation/destruction.
