Abstract

Se describe un proceso de preparacion de materiales multimetálicos a base de metales de transicion, empleando la coprecipitacion de compuestos mixtos provenientes de soluciones que contienen los metales. Se describe un proceso de preparacion de materiales multimetálicos a base de metales de transicion, empleando la coprecipitacion, preferiblemente buscando la condicion de formacion de un gel, a pártir de la mezcla de soluciones precursoras que contienen los metales. Los parámetros del proceso son fijados de manera de resultar un material susceptible de conformacion por extrusion, obteniendo extruídos con propiedades físico-químicas superiores para ser utilizados como adsorbente, como catalizador o soporte para catalizador, o también como relleno de reactor o de columna.
