ABSTRACT:
Process for removing chlorinated hydrocarbons such as ethylene dibromide and PCBs from a material containing the same such as a fuel, hazardous waste material, fuel containing a hazardous waste material, which comprises forming a ternary alloy of sodium, copper and lead by dispersing sodium metal in oil and reacting the same with a catalytic amount of copper and at least the same amount of lead to provide a slurry of said alloy; contacting the material containing the halogenated hydrocarbon with said slurry using an amount of alloy whereby the sodium is present in excess with respect to halogen present; carrying out said contacting at a temperature of about 250.degree.-300.degree. F. under intense mixing and separately recovering the sodium halide, copper-lead and unreacted sodium-copper-lead alloy from the substantially halogen free material.
The invention also contemplates as novel the ternary alloy of Na, Cu and Pb and the oil slurry containing the same.
