Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA LA PRODUCCION DE UNOS CATALIZADORES CON CUBIERTA PORTADORA DE METAL NOBLE, MEDIANTE LA FOTOREDUCCION DE UNOS PRECURSORES DE SAL METALICA NOBLE QUE ESTAN FIJADOS AL PORTADOR, POR MEDIO DE RADIACION ULTRAVIOLETA. ADEMAS, LA PIEZA MOLDEADA PORTADORA ES IMPREGNADA CON UNAS SALES METALICAS NOBLES ADECUADAS, QUE SON DESPUES PREFERENTEMENTE REDUCIDAS EN PRESENCIA DE UN MEDIO DE REDUCCION QUIMICO CON RADIACION ULTRAVIOLETA EN UNA ZONA PROXIMA A LA SUPERFICIE DE LOS METALES. LAS SALES METALICAS NOBLES NO RADIADAS Y, POR TANTO, NO REDUCIDAS EN EL INTERIOR GRANULAR DE LOS PELLETS SON EXTRAIDAS CON UN DISOLVENTE. LOS CATALIZADORES CON CUBIERTA DE METAL NOBLE PRODUCIDOS DE ESTE MODO PUEDEN SER UTILIZADOS PARA UNA GRAN CANTIDAD DE REACCIONES CATALIZADAS HETEROGENEAS TALES COMO HIDROGENACIONES Y OXIDACIONES. LOS CATALIZADORES CON CUBIERTA DE PD/AU PRODUCIDAS CON ARREGLO A ESTE PROCEDIMIENTO PUEDEN SER UTILIZADOS, SEGUN LA INVENCION, SOBRE PORTADORES CERAMICOS POROSOS, POR EJEMPLO, PIEZAS MOLDEADAS DE SIO SUB,2 , EN LA SINTESIS DEL VINILACETATO.
