Abstract
A process for the decomposition of perfluoroalkanes comprises contacting a gaseous stream comprising the perfluoroalkanes with a catalyst comprising alumina. The alumina is prepared from one or more alumina sources, one of which is aluminum nitrate. The catalyst preferably comprises stabilizing agent, in particular zirconium oxide or cobalt, preferably both. The catalyst is prepared by forming a slurry of aluminum nitrate, optionally with one or more additional sources of alumina, in a suitable solvent, such as water. The resulting mixture is dried and calcined to yield the finished catalyst. The stabilizing agent or a precursor thereof may be included in the mixture or impregnated into the finished catalyst.
Claims13
A method for preparing a catalyst for use in the conversion of perfluoroalkanes, which method comprises forming a mixture comprising aluminum nitrate and a solvent, drying the mixture to remove the solvent and calcining the resulting material to yield a catalyst.
A catalyst for use in the decomposition of perfluoroalkanes, which catalyst comprises alumina prepared from aluminum nitrate.
