Abstract

UNA ESTRUCTURA DE DESTILACION CATALITICA (10) QUE TIENE UNA PLURALIDAD DE CATALIZADORES DISPUESTOS VERTICALMENTE Y ONDULADOS QUE CONTIENEN ELEMENTOS (12) SEPARADOS POR ELEMENTO ESPACIADORES INERTES (24). EL CATALIZADOR CONTIENE ELEMENTOS (12) QUE TIENEN CADA UNO DOS CAPAS DE MATERIAL PERMEABLE AL GAS (18,20) COMO UNA MALLA DE ALAMBRE, UNIDOS ENTRE SI EN INTERVALOS ESPACIADOS REGULARMENTE (13) PARA FORMAR UNA SOLA LAMINA (12) CON BOLSAS (22) DISPUESTAS EN LA SUPERFICIE. UN CATALIZADOR DE MICROPARTICULAS (26) SE ENCUENTRA DISPUESTO DENTRO DE LAS BOLSAS (22). ESTE PROPORCIONA UNA ZONA DE REACCION EN LA QUE LAS REACCIONES CATALITICAS PUEDEN PRODUCIRSE, Y LAS LAMINAS PERMEABLES AL GAS (18,22) PROPORCIONAN SUPERFICIES DE TRANSFERENCIA DE MASA PARA EFECTUAR UNA DESTILACION FRACCIONADA. LOS ELEMENTOS ESPACIADORES (14) PERMITEN UNA VARIACION DE LA DENSIDAD Y CARGA DEL CATALIZADOR.
