ABSTRACT:
A catalyst support for use in promoting oxidation reactions composed of metal particles is described. The metal particles are selected from the group of aluminum, tantalum, titanium, tungsten, niobium and mixtures thereof, where aluminum is preferred. The metal particles may have a rough diameter of from 0.02 to 10 mm. The particles may be in the form of spheres, shavings, irregular granules and the like. When the catalyst support is to be used in a tubular reactor, the ratio of the diameter of the reactor to the diameter of the catalyst may range from 1.1 to 200:1. The metal catalyst supports are inert in the reaction and give excellent uniformity in heat distribution throughout the catalyst bed. In oxidation reactions, the catalyst support may bear a metal oxide catalyst to give good results. The particulate catalyst support bearing the active catalyst may also be compressed to inhibit channelling and to help provide higher yield to the desired product. The use of perforated plates within the catalyst bed also aids heat distribution, prevention of channelling and product yield improvement.
