Effect of process parameters on tire pyrolysis: a review

This review presents pyrolysis of scrap tires with a focus on effect of process parameters (reactor temperature, gas flow rate and catalyst-tire ratio) on yield. Three commercially important pyrolysis by-products from scrap tires are carbon residue, pyrolitic oil and pyro-gas. Pyrolysis of scrap tire starts at 250°C and gets completed at 550°C. Presence of catalysts produces lighter oil with a drastic increase in the concentration of single ring aromatics.
