This paper focus on the thermal pyrolysis of used tyre with different catalysts at a temperature 550°C and at a heating rate of 15°C/min. The effect of process parameters on liquid yield, char formation and volatiles were also studied. In the present work, thermal pyrolysis of waste tyre samples with two selected catalysts, namely Jordan zeolite (zeolite Jo) and activated alumina was carried out in a fixed-bed reactor. The catalyst was mixed with feedstock in different percentages (10%, 15%, 25% and 35% w/w). The effects of catalysts and their ratio on the pyrolysis product oil were investigated and the results were compared with the results of experiments performed without catalyst under the same conditions (temperature 550°C at a heating rate of 150C/min). The maximum liquid yield obtained from pyrolysis of waste tyre via catalyst were found as 49.32% and 51.54% on using activated alumina and zeolite Jo as catalysts, respectively, while these values were 42.48%, without catalyst. The mass loss of tyre was examined using the thermo gravimetric analysis profiles (TGA) at heating rate of 15°C/min in air atmosphere from room temperature up to 600°C. The tyre pyrolysis liquid product has been characterized including fuel properties, proximate analysis, and ultimate analysis and FTIR. Fuel properties show that it can be used as liquid fuels.
