Abstract
PROCEDIMIENTO PARA EL TRATAMIENTO DE MONOXIDO DE CARBONO GASEOSO CARGADO CON HUMOS. SE PONE DICHO GAS CARGADO CON HUMOS EN CONTACTO CON PARTICULAS DE CARBONO EN UN LECHO FLUIDIFICADO MANTENIDO A UNA TEMPERATURA SUPERIOR A LA DE FORMACION DEL OXI-CARBONO DE ALUMINIO PEGAJOSO. ESTE PROCEDIMIENTO ES ESPECIALMENTE APROPIADO PARA EL TRATAMIENTO DE LOS GASES DESPRENDIDOS EN LA REDUCCION CARBOTERMICA DE LA ALUMINA PARA LA PRODUCCION DE ALUMINIO, EN CUYO CASO DICHOS GASES CONTIENEN UNA CANTIDAD SUSTANCIAL DE VAPOR DE ALUMINIO Y DE SUBOXIDO DE ALUMINIO.
