Abstract

EN EL PRESENTE ESTADO ACTUAL TECNOLOGICO NO SE CONOCE NINGUN METODO DE SEPARACION DE CANTIDADES GRANDES POSIBLES DE OXIDO DE NITROGENO CON, AL MISMO TIEMPO, UNA PERDIDA DESPRECIABLE DEL AGENTE DE REDUCCION PARA LA CONVERSION CATALITICA DE OXIDOS DE NITROGENO CONTENIDOS EN LOS GASES DE EXHAUSTACION A PARTIR DE UN MOTOR DIESEL UTILIZANDO UN CATALIZADOR DENO{SUB,X}, CONJUNTAMENTE CON UN AGENTE DE REDUCCION, HABITUALMENTE AMONIACO, MEDIANTE EL PROCESO SCR. LA INVENCION PROPONE QUE LA PORCION M{SUB,R} DEL AGENTE DE REDUCCION SE INTRODUZCA DENTRO DEL GAS (10) DE EXAHUSTACION DE FORMA AJUSTADA COMO UNA FUNCION DE AL MENOS UN PARAMETRO RELEVANTE DE OPERACION DEL GAS (10) DE EXHAUSTACION, DE AL MENOS UN PARAMETRO RELEVANTE DE OPERACION DE LA UNIDAD (8) DE CATALIZADOR Y POSIBLEMENTE AL MENOS UN PARAMETRO RELEVANTE DE OPERACION DEL MOTOR (4). ESTO ASEGURA QUE, CUANDO EL AGENTE (16) DE REDUCCION ES DOSIFICADO, LA PORCION DE OXIDO DE NITROGENO M{SUB,NO}{SUB,X}, LA ACTIVIDAD K CATALITICA DE LA UNIDAD (8)DE CATALIZADOR Y DE SU CICLO DE PRESION Y TEMPERATURA, LA CARACTERISTICA DE ABSORCION Y DESABSORCION DE LA UNIDAD (8) CATALITICA Y EL AGENTE (26) REDUCCION ASI COMO EL ENVEJECIMIENTO Y LOS EFECTOS DE PRODUCCION EN LA UNIDAD (8) DE CATALIZADOR SEAN TENIDOS EN CUENTA Y SE CONSIDERE EL EFECTO DE LA PORCION M{SUB,R} DE AGENTE DE REDUCCION A SER AÑADIDA AL GAS DE EXAHUSTACION POR MEDIO DE UNA UNIDAD DE CONTROL. LA INVENCION ES APLICABLE DE FORMA ESENCIAL A TODOS LOS MOTORES DE COMBUSTION INTERNA OPERANDO CON EXCESO DE AIRE PARA REDUCIR EL OXIDO DE NITROGENO EN EL GAS DE EXAHUSTACION.
