Abstract

La presente invención se refiere a catalizadores soprtados del tipo que incluye un soporte obtenido por conformación de un material poroso, en que se depositan elementos catalíticamente activos, caracterizados porque por lo menos uno de estos elementos activos, que no pertencen a la familia del platino, se deposita en forma homogénea en concentración, sobre una corona periférica de ancho determinado del soporte.
