Abstract
ABSTRACT Power generation without environmental impairment is a challenging task for humankind. Presently pyrolysis process using various catalysts is among the finest technologies for generating alternate energy. This research aims to explore the pyrolysis of discarded bus/truck tires with zeolite ZSM-5. A fixed-bed reactor was employed to pyrolyse scrap tires at a temperature range of 300–580°C. Furthermore, it investigates the temperature and catalyst-to-tire ratio impact on the evolved oils’ generation and composition. Density, kinematic viscosity, and gross calorific value of the obtained oil, are analysed. CT ratio has increased the gas generation but decreases oil production. Elemental analysis of pyrolytic liquid oil revealed carbon percentage increment and decrement of sulphur percentage when CT ratio was increased. FT-IR showed data revealed the strong presence of aromatic compounds and other valuable hydrocarbons in the upgraded pyrolytic oils. The pyrolytic oil showed provided a high calorific value of 40.38 MJ/kg, comparable to conventional diesel oil of 42 MJ/kg. GC-MS analysis identified a higher amount of o-xylene, toluene, naphthalene, and d-limonene in derived oil when the CT ratio of the process was increased from 0.1 to 0.25, denoting the capability of the evolved oil as an alternative energy source and value-added chemical substances.
