What is pyrolysis oil characteristic?
Pyrolysis is a complex series of chemical and thermal reactions to decompose or depolymerize organic material under oxygen-free conditions. The products of pyrolysis include oils, gases and char. The pyrolysis oil products in this research are from tire and plastic which are dissimilar in physical properties and chemical properties. The appearance of the tire pyrolysis oil is thick-liquid and dark colour oil where as the appearance of the plastic pyrolysis oil is grease oil liked and dark colour oil at 30°C (room temperature). They all strong smell due to the high aromatic substance. As the comparison usage of this research is in diesel engine, the pyrolysis oil from process is a mixture of carbon composition which are C 5-C 20 in tire pyrolysis oil and C 10-C 30 in plastic pyrolysis oil. The oil requires dis- tillation process to differentiate the diesel-like oil from other compounds. The distillation temperature applied in this research is 180°C. The substance that evaporates before 180°C is taken out. The remaining is analyzed and tested in one cylinder multipurpose agriculture diesel engine. The properties comparison of plastic oil, tire oil and diesel oil is analyzed as shown in Table 2. The proximate analysis was conducted using a thermo-gravimetric analyzer. The elemental determination (carbon, hydrogen, nitrogen and sulfur content) are ana- lyzed by a CHNS Elementary Analyzer. The chlorine content of PVC was determined by improved oxygen bomb combustion - ion chromatography method which is based on the standard method in ASTM D 4208-02. The heating value of all the samples was measured using bomb calorimeter.
The heating value and the flash point of plastic pyrolysis oil is the highest while the other properties are comparable. As the plastic pyrolysis oil is wax form in room temperature, the oil requires pre-heating process before input to diesel engine.
