Abstract

ESTA INVENCION SE REFIERE A UN CATALIZADOR QUE CONTIENE PALADIO EN UN SOPORTE (102) Y A UN PROCESO DE COMBUSTION PARCIAL EN EL QUE EL COMBUSTIBLE SE QUEMA PARCIALMENTE UTILIZANDO ESE CATALIZADOR. EL CATALIZADOR DE PALADIO (106) PUEDE CONTENER TAMBIEN PALADIO MEZCLADO CON METALES SELECCIONADOS DEL GRUPO VIII O IB, SE PUEDE GRADUAR (FIG. 1B) DE MANERA QUE TENGA UNA MAYOR ACTIVIDAD EN EL BORDE ANTERIOR (112) DEL CATALIZADOR O SE PUEDE COLOCAR EN UN SOPORTE QUE CONTENGA ZIRCONIA. CADA UNA DE LAS ELECCIONES DE LOS CATALIZADOR (106) Y SOPORTES (102, 110) ESPECIFICADOS RESUELVE LOS DISTINTOS PROBLEMAS QUE TIENEN QUE VER CON LA ESTABILIDAD A LARGO PLAZO DEL PALADIO COMO CATALIZADOR DE COMBUSTION PARCIAL. LA ESTRUCTURA DEL CATALIZADOR ES ESTABLE CUANDO SE ENCUENTRA EN FUNCIONAMIENTO, TIENE UNA TEMPERATURA DE FUNCIONAMIENTO COMPARATIVAMENTE BAJA, LA OXIDACION EMPIEZA A UNA TEMPERATURA BAJA Y AUN NO SE PRODUCE UN "EMBALAMIENTO" DE LA TEMPERATURA. EL GAS DE COMBUSTION PRODUCIDO POR EL PROCESO CATALITICO TIENE NORMALMENTE UNA TEMPERATURA INFERIOR A LA TEMPERATURA DE AUTOCOMBUSTION Y SE PUEDE UTILIZAR A ESA TEMPERATURA O SE PUEDE ALIMENTAR A OTROS ESTADOS DE COMBUSTION PARA UTILIZARLOS TAMBIEN EN UNA TURBINA DE GAS, UN HORNO, UNA CALDERA O SIMILAR.
