Abstract

PROCEDIMIENTO DE PREPARACION DE UN CATALIZADOR DE PLATA SOPORTADO UTILIZADO EN LA PRODUCCION DE OXIDO DE ETILENO. SE IMPREGNA UN SOPORTE DE CATALIZADOR POROSO, CON DIAMETRO DE POROS ENTRE 0,5 Y 50 MICRAS, CON UNA SOLUCION DE PLATA COMPUESTA DE UNA SAL DE PLATA, COMO NITRATO DE PLATA, Y UN DISOLVENTE O ANGENTE COMPLEJANTE/SOLUBILIZANTE, COMO ACIDO LACTICO, Y CON SALES DE CESIO Y POR LO MENOS OTRO METAL ALCALINO SELECCIONADO ENTRE LITIO, SODIO, POTASIO O RUBIDIO. SE ESCURRE LA TOSTACION A UNA TEMPERATURA ENTRE 200 Y 700 GRADOS C CON LO QUE SE DEPOSITAN LOS IONES DE LOS METALES ALCALINOS Y PLATA METALICA, CON UNA CONCETRACION DEL 6 AL 16 POR 100 EN PESO DE PLATA.
