CA 2415833

A process for the catalytic oxidation of a feed comprising contacting said zone, wherein: (a) said catalyst comprises at least one catalytically active metal selected from the group consisting of silver and the elements of Group VIII of the Periodic Table of the Elements supported on a porous ceramic carrier, (b) said catalyst is retained within said reaction zone in a fixed arrangement; and (c) said carrier has a distribution of total pores wherein: (1) about 70 percent of said total pores have a volume to surface area ratio (V/S) that is within about 20 percent of the mean V/S value for said total pores and no pores have a volume to surface area ratio that is greater than twice the mean V/S value for said total pores; and (2) for about 70 percent of said total pores, the pore-to-pore distance between neighboring pores is within about 25 percent of the mean pore-to-pore distance between neighboring pores; and (3) about 50 percent of said total pores have a coordination number that is within about 50 percent of the mean coordination number between neighboring pores and wherein less than about 15 percent of said total pores have a coordination number that is less than 3.

L'invention porte sur un procédé d'oxydation catalytique d'une charge consistant à mettre en contact cette charge. Selon ce procédé, (a) le catalyseur comprend au moins un métal actif d'un point de vue catalytique sélectionné dans le groupe comprenant l'argent et les éléments du groupe VIII du Tableau Périodique des Eléments supportés sur un support céramique poreux ; (b) ce catalyseur est retenu dans la zone de réaction d'un dispositif fixe ; et (c) la répartition de la totalité des pores du support est: (1) environ 70 % de la totalité des pores ont un rapport volume/superficie (V/S) compris dans une limite d'environ 20 % de la valeur moyenne de V/S pour la totalité des pores et aucun pore n'a un rapport volume/superficie supérieur à deux fois la valeur moyenne de V/S ; et (2) pour environ 70 % de la totalité des pores, la distance pore à pore entre pores voisins est d'environ 25 % de la distance moyenne pore à pore entre pores voisins ; et (3) environ 50 % de la totalité des pores a un nombre de coordination d'environ 50 % du nombre de coordination moyen entre pores voisins et environ moins de 15 % de la totalité des pores a un nombre de coordination inférieur à 3.
