Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA DISMINUCION DEL MONOXIDO DE CARBONO, OXIDOS DE NITROGENO E HIDROCARBUROS CONTENIDOS EN LOS GASES DE ESCAPE DE MOTORES ENDOTERMICOS. SE TRATAN LOS GASES EN TRES FASES SUCESIVAS, PRIMERO SE HACEN PASAR, POR UNA MASA DE CARBON ACTIVADO, EN BASE A HULLA SUB-BITUMINOSA, IMPREGNADA CON UN COMPUESTO HALOGENADO A BASE DE CLORO O BROMO, LUEGO HACIENDOLOS PASAR A TRAVES DE UNA MASA ANALOGA, IMPREGNADA POR UNA SUSTANCIA TIPO ACIDO DE LEWIS, Y FINALMENTE SE HACEN CIRCULAR A TRAVES DE UNA MASA ANALOGA, IMPREGNADA CON UNA SUSTANCIA TIPO BASE DE LEWIS. EL DISPOSITIVO COMPRENDE ESENCIALMENTE UNA SERIE DE TRES CAMARAS (1, 2, 3), EN BATERIA, CON SISTEMA ENFRIADOR (4), Y LLEVAN EN SU INTERIOR LAS MASAS FIALTRANTES (10, 11, 12) DEL TIPO INDICADO, PRESENTANDO LA PRIMERA (1), CONDUCTOS DE ENTRADA (13) Y SALIDA (14), EL PRIMERO CON VALVULA DE PASO (15), Y OTRO CONDUCTO (16) DE EVACUACION DE LOS CONDENSADOS.
