This review evaluates the effects of four key parameters-pyrolysis temperature, heating rate, vapor residence time, and reactor type-on waste-tire pyrolysis. At 500 °C, an oil yield of 43.6 wt.% was reported, while increasing the temperature to 750 °C reduced oil yield to 26.6 wt.% and increased gas yield to 33.5 wt.%. Increasing the heating rate from 5 to 25 °C min-1 decreased oil yield from 54.8 to 43.0 wt.%, whereas gas yield increased from 7.24 to 18.04 wt.%. These results demonstrate that operating conditions strongly control product distribution and physicochemical properties. The optimal conditions therefore depend on the targeted recovery of oil, gas, or carbonaceous products.
