Abstract
Un sistema catalizador de tres pasos para convertir en forma eficiente los gases de escape de motores con combustible CNG cuando se operan en condiciones pobres con una relación reductora de .02-.9, el sistema comprende un catalizador de primer paso que comprende una zeolita metálica de transición; un medio para la inyección de hidrocarburo en dicho gas de escape antes de la entrada de dicho gas de escape en dicho catalizador de primer paso, dicho hidrocarburo tiene una afinidad mayor que CH4 en su habilidad para reaccionar con NO; y un catalizador de segundo paso para el tratamiento del efluente de dicho catalizador de primer paso y que comprende una superficie alta de alúmina impregnada con La2O3 discontinuo y paladio.
