Experimentation and Evaluation of Tyre Pyrolysis Oil

Abstract

Scrap tyre consists of organic matter that is often disposed illegally in open lands, ultimately causing an environmental problem. Pyrolysis is considered as a useful technique for recycling of scrap tyres by using which liquid, gases, carbon black and steel wires are obtained. The difficulty in using Tyre Pyrolysis Oil (TPO) as an energy source is its complex chemical composition. The following report discusses about how the oil can be effectively utilized by separating it according to composition using the process of fractional distillation. From 1.5 Litre of TPO 350 ml of distilled oil is obtained in the temperature range of 200-270 0C which is blended with diesel to be used as high grade fuel to run a DI 4 stroke single cylinder diesel engine. The TPO left in the flask after distillation is found to have high viscosity, high fire point and high pour point; as a result of which it is utility is found in being used as a base for manufacture of lubricants. By employing such techniques the commercial value of TPO is increased and also better results were obtained. With increase in utility of TPO it is expected that more such manufacturing plants will come up. This will help to recycle more percentage of waste tyres from among the 1 billion scrap tyres generated each year around the world.
