Abstract

UN METODO PARA SINTETIZAR UNA ZEOLITA UNIDA A UN SUSTRATO, UTILIZA UNA MEZCLA DE REACCION, QUE TIENE UNA PROPORCION MOLAR DE H2O/YO2 DE, AL MENOS, 25 E Y ES ELEMENTO TETRAVALENTE, ESPECIALMENTE SILICIO. UNA ESTRUCTURA HECHA CONFORME A ESTE METODO INCLUYE UNA PELICULA DE CRISTALES DE ZEOLITA INTERCONECTADOS, UNIDOS A UN SUSTRATO, Y LA ESTRUCTURA SE CARACTERIZA POR UN VALOR R, REPRESENTANDO EL MG DE ZEOLITA/CM2 DE SUPERFICIE DEL SUSTRATO, Y UN VALOR 2, REPRESENTANDO LA EFICACIA DEL REVESTIMIENTO COMO MG DE ZEOLITA UNIDA/MG DE YO2 INICIALMENTE EN LA MEZCLA DE SINTESIS; DONDE R ES AL MENOS 0''5 Y E ES AL MENOS 0''05. SE FACILITAN PROCESOS PARA SEPARACION, SORBCION, CONVERSION DE PRODUCTOS ALIMENTICIOS ORGANICOS Y CONVERSION DE NOX SOBRE LA ESTRUCTURA.
