A process is disclosed which comprises: contacting a catalyst such as alumina silica, aluminosilicates, titanium oxide, magnesium oxide, and the metals of Groups III and IIB of the Periodic Table under reducing conditions with a gaseous mixture comprising elemental chlorine gas and a diluent under conditions effective to improve the ability of the catalyst to dehydrohalogenate halogenated hydrocarbons: contacting the catalyst with a halogenated hydrocarbon feedstock, the halogenated hydrocarbon feedstock with or without a carrier gas, in the gas phase under dehydrohalogenation conditions; and recovering a dehydrohalogenated product. |
