The depletion of fossil fuels has prompted research into alternative fuels made from regeneration of waste materials. Pyrolysis is a method of converting waste oil into valuable products, such as char, gas, and fuel. This study presents the catalytic pyrolysis of waste oil for producing fuel utilizing cerium oxide, CeO2/Al2O3 and zinc oxide, ZnO/ Al2O3 catalyst. The catalyst and oil were characterized using several characterization techniques to find the physicochemical properties of the catalyst and oil. The optimum condition for catalytic pyrolysis was a reaction temperature at 500℃, with the heating rate at 10 oC/min, utilizing CeO2/Al2O3 catalyst calcined at 700℃. The catalytic pyrolysis successfully converted the waste oil into fuel and the oil product obtained was 93.01 wt% with a high calorific value (54.2MJ/kg). The pyrolysis oil is comprised of aliphatic hydrocarbon (C5-C15 hydrocarbon) that is within the hydrocarbon range for gasoline and diesel. The oil product was also detected to have a low content of oxygen (3.07 wt%) and sulfur (0.60wt%), indicating its potential to serve as a cleaner, fuel reducing the sulfur dioxide, SOX formation. The results reveal that pyrolysis reactors have the ability to convert waste oil into hydrocarbon fuel.
