Abstract:
A process for the decomposition of perfluoroalkanes to HF and CO.sub.2, said process comprising:contacting, at a temperature of at least 500.degree. C. and in the presence of oxygen, the perfluoroalkanes with a catalyst composition consisting essentially of aluminum oxide, cobalt and zirconia, wherein,(1) said aluminum oxide contains at least a catalytically effective amount of gamma phase alumina,(2) said zirconia is present in an amount between an amount effective to stabilize the aluminum oxide and up to about 3, weight % and(3) said cobalt is present in an amount between an amount effective to stabilize the aluminum oxide and up to about 5 weight %, based upon the weight of the total catalyst composition.
