    • C.sub.2 -C.sub.4 halogenated, e.g., chlorinated and brominated, hydrocarbons, such as vinyl chloride, present in a gas stream are removed therefrom, e.g., incinerated, by contacting the gas stream with an oxygen-containing gas in the presence of cobalt oxide catalyst at relatively low temperatures, e.g., 100.degree. C. Commonly, the halogenated hydrocarbon is present in the gas stream to be treated in small amounts, e.g., less than 0.05 weight percent. The temperature of treatment can vary, e.g., from 20.degree. to 500.degree. C., and can be adjusted within said range depending on the relative humidity of the gas stream treated to maintain catalytic activity. Preferably, treatment occurs under conditions of low relative humidity, e.g., less than 5 percent, and the catalyst is a hydrated cobalt oxide catalyst.
