Studies on pyrolysis oil derived from waste tires as fuel for diesel engine

Abstract

In recent years, the number of automotive vehicles are increasing as these vehicles are becoming essential in developed and developing countries; which results in increase in waste tires. In most of the developing and under developed countries, the waste tires are not scientifically disposed and pollutes the environment. The synthetic rubber present in the tire is not biodegradable. Hence a research work is carried out to convert the waste tires and tubes into fuel using the process of pyrolysis. The tire pyrolysis oil (TPO) properties were compared with fossil diesel and it was observed that the properties of tire pyrolysis oil and diesel are closer. In the diesel engine the tire pyrolysis oil was used as partial substitute for the diesel and engine tests were performed by varying the engine loads. The results of the engine tests show that the tire pyrolysis oil can be effectively used as partial substitute in diesel engine with no need of making modifications in the engine's fuel injection system. This paper discusses the waste tire statistics, conversion of tire into tire pyrolysis oil and engine studies with tire pyrolysis oil.
