Fractional Distillation & Characterization of Tire Derived Pyrolysis Oil

Abstract

Energy is extracted recently from the waste products. Environmental pollution is being minimized along with the addition of considerable amount of energy beside the conventional sources. The energy extracted from the waste leads a hope of alternative fuel for internal combustion engines as well as to meet other requirement. Common energy conversion method uses tire, wood, rubber to derived energy through pyrolysis. About 9.25% gaseous, 43% liquid and 47% solid product are obtained for tire pyrolysis process at around 450 °C temperature. The liquid fuel is directly used in the engines and there phase is a mixture of complex hydrocarbon. In this work Fractional Distillation, oxidative desulfurization and de-colorization for upgrading liquid product has been conducted. In fractional distillation 30%, 20%, 6.35%, 6%, 4.5% and 1.3% by volume oils are obtained at over the temperature ranges- 121-180 oC, 211-260 oC, 71-120 oC, 191-210 oC, 181-190 oC and 40-70 oC. Then by desulfurization around 54-58 % sulfur was removed. For desulfurization hydrogen peroxide and formic acid (2:1 ratio) are used at constant temperature and magnetic stirring rate. The obtained fraction were characterized by elemental analyses, FT-IR techniques and compared with conventional diesel fuel. Sludge oil parts may be used as furnace oil which has higher calorific value than that of other conventional furnace oils. The rest of 40-70 oC and 71-120 oC oil parts may be used as alternative fuel like kerosene. Thus, the aim of the present study is to investigate the suitability of pyrolysis oil as an alternative fuel for IC engine.
