Abstract:
A process for the partial catalytic oxidation of a hydrocarbon containing feed comprising contacting said feed with an oxygen-containing gas in the presence of a catalyst in a reaction 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 a 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) about 70 percent of said total pores have a pore-to-pore distance between neighboring pores that is within about 25 percent of a 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 a 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.
