Abstract
PROCEDIMIENTO PARA REDUCIR MENAS METALICAS EN FORMA DE PARTICULAS EN METAL ESPONJOSO Y APARATO CORRESPONDIENTES. CONSISTE EN HACER PASAR UN GAS REDUCTOR CALIENTE, CONSTITUIDO FUNDAMENTALMENTE POR MONOXIDO DE CARBONO E HIDROGENO, A TRAVES DE LA MENA EN UN REACTOR; DESHIDRATAR EL GAS DE SALIDA; RECICLAR UNA PARTE DEL MISMO; INTRODUCIR GAS REDUCTOR COMPLEMENTARIO, PROCEDENTE DE LA TRANSFORMACION DE UN GAS QUE CONTIENE HIDROCARBUROS, EN UN CONVERTIDOR CATALITICO A TEMPERATURA ELEVADA, QUE SE CALIENTA POR COMBUSTION DE OTRO COMBUSTIBLE. LOS PRODUCTOS DE COMBUSTION, CALIENTES, INTERCAMBIAN CALOR CON LOS GASES QUE SALEN DEL REACTOR EN UNA CAMARA DE CALENTAMIENTO.
