Characterization of Upgraded Pyrolytic Oil by Using ZSM-5 Catalyst in Thermal Pyrolysis of Scrap Tire

Relentlessness of energy predicament and environmental degradation are the two most vital problems across the globe; and, hence, are alarming issues. This is true for Bangladesh also. Nowadays recycling of scrap tire has emerged as a solution for minimizing energy crisis in one hand and eradication of environmental pollution on the other hand. In this backdrop, a catalytic pyrolysis experiment has been conducted taking scrap tires which were pyrolysed in a fixed bed reactor at 300-600C in the presence of ZSM-5 Zeolite. The density, viscosity, calorific value, flash point and pour point of the characterized pyrolytic oil were 915.84 kg/m, 6.35 cSt, 38.27 MJ/kg, 35C and -11C. Moreover, the effect of catalyst on the process of oil extraction and the composition of the pyrolysis oil was also investigated. It is found that, with escalating catalyst/tire ratio and pyrolysis temperature, there occurs decrease in yield of oil and char production and increase in yield of gas.
