Fuel properties of pyrolytic tyre oil and its blends with diesel fuel - Towards waste management

The non-biodegradable nature of scrap tyres makes it not suitable for landfills. In this study thermal pyrolysis of waste tyre samples was carried out in a semi batch reactor made up of stainless steel in our own laboratory .The physiochemical properties of tyre pyrolysis oil (TPO) had been studied by different analysis .The oil samples obtained from waste tyre is distilled and then mixing with common diesel oil were analysed according to their fuel properties, elemental analysis and functional groups presents. The products from the tyre pyrolysis are (33-39) wt. % char, (34-42) wt. % oil, and except are uncondensed gases. Almost 44.5% TPO can be distilled as fuel oil. The comparative study of physiochemical properties and Fourier transform infrared spectroscopy (FTIR) analysis of distilled tyre pyrolysis oil (DTPO) and diesel oil is also present in this paper. The blended oil (50% DTPO+ 50% diesel) shows almost similar properties with conventional diesel oil except flash point and fire point.
