Abstract
A process and composition for transforming perfluoroalkanes in the presence of an oxidizing agent and water at temperatures between about 400 to 1,000.degree. C. Aluminum oxide is the primary agent for effecting this transformation. Additions of between 0.1 to 50% by weight of other components such as barium calcium, phosphorus, cerium, chromium, cobalt, iron, lanthanum, magnesium, nickel, silicon, titanium, yttrium or zirconium aid in extending the useful life of the catalyst. A preferred catalyst composition includes aluminum oxide with additions of cobalt and one or more of the elements of cerium, titanium or zirconium.
