This patent describes a process for the dehalogenation of polyhalogenated hydrocarbons from an oil containing same wherein the dehalogenation is carried out through the reaction of sodium or potassium. The improvement is described which comprises contacting a dispersion of sodium or potassium over the surface of a particulate inert material having a density of at least 2.0 with a polyhalogenated hydrocarbon contaminated hydrocarbon fluid, the mixture being in an inert atmosphere, heated to a temperature of at least 100/sup 0/C. and under constant agitation. The sodium or potassium coated on the surface of the particulate inert material reacts with the halogen of the polyhalogenated hydrocarbon to form the corresponding sodium or potassium halide which is constantly removed from the active surface of the sodium or potassium by abrasion and recovering the hydrocarbon fluid substantially devoid of polyhalogenated hydrocarbon.
