Abstract

SE DESCRIBEN MEMBRANAS COMPUESTAS QUE TIENEN UNA CAPA DE SEPARACION CONSTITUIDA POR UNA MEZCLA DE POLI(METACRILATO DE METILO) O UN COPOLIMERO DEL MISMO Y AL MENOS UN DERIVADO CELULOSICO QUE DA COMO RESULTADO CARACTERISTICAS MEJORADAS DE SEPARACION Y PERMEACION DE LA MEMBRANA COMPUESTA GLOBAL. SE DESCRIBEN TAMBIEN PROCEDIMIENTOS PARA FABRICAR ESTAS MEMBRANAS COMPUESTAS Y LOS METODOS PARA FABRICAR ESTAS MEMBRANAS COMPUESTAS Y LOS METODOS DE UTILIZACION DE LAS MISMAS. LAS MEMBRANAS SON PARTICULARMENTE UTILES EN APLICACIONES DE SEPARACION DE GASES Y SON SUMAMENTE ADECUADAS PARA LA SEPARACION DE HIDROGENO A PARTIR DE UNA CORRIENTE QUE CONTENGA HIDROGENO.
