    Waste tire pyrolysis oil has high potential to replace conventional fossil liquidfuels due to its high calorific heating value, However, the large amounts of sulfurous compounds in this oil hinders its application. Thus, the aim of this review study was to investigate the possibility to apply the additives like CaO, CaCO3and acids like phosphoric acid H3PO4, acetic acid CHCOOH, formic acid HCOOH with clay, at different operating conditions to partially remove sulfurous compounds in the waste tire pyrolysis oil under milder reaction conditions without hydrogen consumption. This review study was carried out for Pyrolytic oils produced in a local tire pyrolysis plant at Jenin Governorate, and for the oil that was produced by thermal and catalytic cracking designed by Dr_shadisawalha and his students. The use of phosphoric acid (8 wt.%) was found more economical and effective in desulfurization and improvement of diesel ,lubricating fuel properties of sample oils. The contribution of lime stone CaCO3(5wt%) additive during pyrolysis process was found effective in improvement of diesel, kerosene and lubricating fuel properties of sample oils.Calcium oxide additive to pyrolytic oil was not found to be effective in desulfurization while calcium oxide(5wt%) additive during pyrolysis process was found effective in desulfurization and improvement of lubricating fuel properties of sample oils.
