The application of coupled thermogravimetric techniques allowed obtaining interesting information regarding NSR thermodynamic and kinetic for Pt-Ba/gamma-Al2O3, Pt-K/gamma-Al2O3 and Pt-Ba-K/gamma-Al2O3 catalysts. The materials have been tested for simultaneous NOx and soot removal according to standard TRM protocol and soot combustion runs. The catalysts presented high performance in the individualized reaction of NOx reduction, soot oxidation and the simultaneous NOx and PM removal. The apparent activation energy calculated follows the order: Pt-Ba > Pt-Ba-K > Pt-K for O-2 and NOx assisted soot combustion, being strongly influenced by the alkali element incorporation that shifts the maximum exothermal process to low temperature, improving the soot removal process.
