Recovery of value added fuels from waste polyolefins bicycle tyre and tube

Pradhan, Debalaxmi (2011) Recovery of value added fuels from waste polyolefins bicycle tyre and tube. MTech by Research thesis.



Thermal pyrolysis is one of the renewable technologies where waste tyre and tube were pyrolysed into fuel oil, carbon lack, and combustible gas under the action of reasonable technological conditions. This technology could not only reasonably and effectively dispose waste tyre and tube without pollution, but also is effective in producing fuel that can reduce energy crisis. In the present work, thermal pyrolysis of waste bicycle tyre and tube samples were arried out in a semi batch reactor made up of stainless steel ithin the temperature range of 450ºC to 800ºC. The optimum yrolytic oil of 49.6%was obtained at 600ºC for tyreand 9.65% for tube at 700ºC. Again to increase further oil ield, different catalysts have been used .e.SiO2/Al2O3, Kaolin, CaO, and MgO. But, it was identified that theatalyticpyrolysis was not effective when compared to thermal pyrolysis in terms of product yields (oil).The physical properties of the oil obtained were determined by using standard test methods and the chemical composition was analyzed by using FTIR, GC-MS analyzer. The char obtained was characterized for its calorific value and surface morphology by SEM. Characterization of both pyrolytic oil shows that the obtained oil is a mixture of diesel and gasoline. The composition of the oil showed the presence of aromatic and aliphatic compounds. Kinetic parameters of tyre and tube sample were also studied at the heating rates of 10, 15and 20ºC/min by TGA which showed that with the increase of rate of heatingactivation energy decreases. Engine performance test was done by using different blends such as 10%, 20%, 30%, 40% and 50% of bicycle tubepyrolyticoil with diesel. Performance, emission and combustion characteristics of the diesel engine were tudied. From engine test it was concluded that 40% blend of tube pyrolytic oil with diesel can be substituted with diesel. After proper treatment these oil can be used as substitute of alternative fuel.
