Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA REDUCCION AL MISMO TIEMPO DE LOS HIDROCARBUROS, MONOXIDO DE CARBONO Y OXIDO DE NITROGENO CONTENIDOS EN EL GAS DE ESCAPE DE MOTORES DE COMBUSTION INTERNA, BIEN SEA DE GASOLINA O MOTORES DIESEL, CON ALTO CONTENIDO DE OXIGENO EN EL GAS DE ESCAPE. ES POSIBLE UN ALTO EFECTO A REDUCCION PARA EL OXIDO DE NITROGENO MEDIANTE LA UTILIZACION DE UN SILICATO DE ALUMINIO COMO MATERIAL SOPORTE DE ALTA SUPERFICIE PARA EL PROCESO CATALIZADOR DE COMPONENTES ACTIVOS.
