A process for reducing a chloride content of a hydrocarbon feed stream involving contacting a hydrocarbon feed stream comprising a chloride containing pyrolysis oil obtained by cracking a chloride containing thermoplastic material with a sulfided catalyst comprising at least one of Co, Mo, and Ni or a catalyst comprising Pd, Pt, Cu, and/or Zn on a catalyst support in the presence of hydrogen gas to reduce one or more organic chloride compounds present in the hydrocarbon feed stream and form a hydrocarbon product stream and HCl. The HCl is removed from the hydrocarbon product stream, wherein the hydrocarbon product stream has a lower chloride content than the hydrocarbon feed stream based on the total weight of the chloride and the total weight of the hydrocarbon feed stream.
