Effect of Process Parameters on the Production of Pyro-oil from Waste Tyres

Abstract: Waste tyres are one of the major causes of environmental pollution, their non-biodegradability nature contributes to hazardous adverse effect they have on the environment. An estimated of 1.5 billion tyres are discarded annually all over the world. In this research, waste tyres were pyrolysed in a fixed bed pyrolyser reactor at 350- 450 ˚C to produce pyro oil as the main desired product. The effect of time of extraction, quantity of gas consumed and quantity of catalyst on percentage oil yield were investigated. The oil yield obtained from the process was found to be 31.1%. The pyro oil properties include: a viscosity of 2.08 cSt, density of 924 kg/m3, flash point of 65 ˚C, pour point of -13˚C, cetane number of 63.19 and calorific value of 37.68 MJ/kg.
