Stabilization and regeneration of activated carbon supported palladium chloride catalysts in the oxidation of vinyl halides

摘要

PdCl.sub.2 /C catalyst which has been deactivated in the oxidation of an olefinic halide or olefinic hydrocarbon present as contaminant in air or other inert oxygen-containing gas stream, is regenerated by prolonged exposure to air or other oxygen-containing gas stream at temperatures below 70° C. and preferably below 60° C.
