Abstract

PROCEDIMIENTO PARA LA ELECTROLISIS DE HALUROS ACUOSOS PARA GENERAR HALOGENO EN ESTADO ELEMENTAL. SE ELECTROLIZA UN HALURO ENTRE UN PAR DE ELECTRODOS SEPARADOS POR UNA MEMBRANA INTERCAMBIADORA DE IONES QUE TIENE UNA SUPERFICIE EMBASTECIDA EN EL LADO CATODICO, APOYANDOSE SOBRE DICHA SUPERFICIE EMBASTECIDA UN CATODO PERMEABLE A LOS GASES Y A LOS LIQUIDOS, ENCONTRANDOSE EN CONTACTO SIN UNIR CON LA MISMA. DICHO CATODO FORMADO POR UNA LAMINA ELECTROCONDUCTORA FORAMINOSA, QUE ES LA QUE ESTA EN CONTACTO CON LA SUPERFICIE EMBASTECIDA, Y UNA SEGUNDA LAMINA ELECTROCONDUCTORA FORAMINOSA EN CONTACTO CON LA PRIMERA LAMINA, TENIENDO LA SEGUNDA UNA SOBRETENSION DE HIDROGENO MAS BAJA QUE LA PRIMERA.
