Abstract

METODO PARA PURIFICACION DE GASES DE ESCAPE. CONSISTEN EN TRATAR EL GAS DE ESCAPE QUE CONTIENE LAS MATERIAS PRIMAS, EN UN REACTOR CON AMONIACO, A UNA TEMPERATURA COMPRENDIDA ENTRE 250JC Y 450JC, EN PRESENCIA DE UN CATALIZADOR CONSTITUIDO POR OXIDO DE HIERRO, OXIDO MIXTO DE HIERRO Y CROMO O UNA MEZCLA DE OXIDO MIXTO Y OXIDO DE HIERRO EN BASE A SUSTANCIAS NATURALES. SE REDUCEN ASI POR EL AMONIACO LAS IMPUREZAS DE FORMALDEHIDOS, MONOXIDO DE CARBONO, OXIDOS NITRICOS Y EL ACIDO PRUSICO. TIENE APLICACIONES PARA LIMPIAR LOS GASES DE ESCAPE DE UN MOTOR DE COMBUSTION OTTO A GAS, O DE UN MOTOR DIESEL, O DE UN QUEMADOR DE GAS LIQUIDO.
