Abstract

UN CUERPO POROSO DERIVADO DE UN MATERIAL POLIMERO, P.EJ. UN MATERIAL POLIMERO QUE FORMA GEL, TENIENDO DICHO CUERPO UNA ESTRUCTURA RETICULADA TRI-DIMENSIONAL DE CELULA ABIERTA, UNA DENSIDAD DE MENOS DE ALREDEDOR DE 1,0 G/CC (CENTIMETRO CUBICO) Y UN AREA SUPERFICIAL IGUAL A O MAYOR QUE ALREDEDOR DE 85 M (AL CUADRADO) /G. DE ACUERDO CON OTRA FORMA DE REALIZACION PRACTICA UN METODO PARA LA REALIZACION DE UN MATERIAL DESEADO, TAL COMO METAL(ES), A PARTIR DE UNA CORRIENTE FLUIDA QUE EMPLEA UNO O MAS CUERPOS POROSOS DE ESTA INVENCION ASI COMO EL MATERIAL DE CONTACTO QUE RECUPERA EL MATERIAL DESEADO DE LA CORRIENTE FLUIDA.
