International Classification:
C01B 302
US Classification:
4236481, 4234371, 423651, 4234182, 252373
Abstract:
A process for the partial catalytic oxidation of a hydrocarbon containing feed comprising contacting the feed with an oxygen-containing gas in the presence of a catalyst retained within a reaction zone in a fixed arrangement, wherein the catalyst comprises at least one catalytically active metal selected from the group consisting of silver and Group VIII elements supported on a porous ceramic carrier. The porous ceramic carrier has a distribution of total pores wherein about 70% of the total pores (1) have a volume-to-surface area (V/S) ration that is within about 20% of the mean V/S value for the total pores and no pores have a V/S ration that is greater than twice the mean V/S value for the total pores; (2) have a pore-to-pore distance between neighboring pores that is within about 25% of the mean pore-to-pore distance between neighboring pores; and (3) have a pore throat area that is within about 50% of the mean pore throat are for the pores. Additionally, about 50% of the total pores have a coordination number between neighboring pores that is within about 25% of the mean coordination number between neighboring pores. Preferably, the oxidation process comprises a multistage, staged oxygen, catalytic partial oxidation process having fewer than or equal to about five stages and including a first stage preheat temperature of greater than about 550Â C.
