Abstract
Recycling of used tyres has been valued by governments of all countries because the pollution caused by these waste tyres has become a rigorous subject in global environmental protection. In the present work, thermal pyrolysis of bicycle waste tyre samples was carried out in a semi batch reactor made up of stainless steel in a temperature range of 450°C to 650°C at a heating rate of 20 0 C/min. The optimum liquid yield was obtained at 600°C for the pyrolysis of bicycle tyre at the feed size of 1cm. Effect of heating rate on the mass loss of tyre was examined using the thermo gravimetric analysis profiles (TGA) at a heating rates of 20°C/min. The tyre pyrolysis liquid product has been characterized including fuel properties, proximate analysis, and ultimate analysis, FT- IR, GC-MS. Fuel propertiesand chromatography studies show that it can be used as liquid fuels and chemical feed stocks, with obtained calorific value of 34.61MJ/Kg and empirical formula of CH 1.32 N 0.01 S 0.02 O 0.42 .
