(40b) Purification of Tire Pyrolytic Oil (TPO) and Its Comparison with Diesel Fuel

Due to growing population and rapid industrialization the global demand for industrial rubber products is increasing. This increase in demand for rubber products has led to the increase in global rubber production which has devastating environmental effects. Disposal of waste rubber products is becoming an environmental challenge due to its non-bio degradability. The majority of the waste rubber product is generated from the worn out, damaged or discarded automotive tires also known as scrap tire. Approximately 1.5 billion tires are produced each year which eventually end up in the waste stream. Scrap tire consists of organic matter that is often disposed illegally in open lands, ultimately creating a big pollution hazard to environment and hygiene. Pyrolysis is considered as a useful technique for recycling of scrap tire by which oil, gas, carbon black and steel wires are obtained. Pyrolytic oil is currently receiving renewed interest as an alternative to fossil diesel fuel. In the present work, crude TPO obtained from vacuum pyrolysis method was purified via de-sulfurization followed by simple distillation. Decolorization and deodorization of the oil was also done to make it suitable for the industry. 30-35% of purified oil (product) was obtained after processing. A comparison of different properties of oil is done before and after purification. Properties of the purified TPO are also compared with diesel fuel for its suitability in diesel engines.
