The standard temperature range for waste-rubber pyrolysis has been reported as 480 – 1,740ºF. Within 480 – 750ºF, shredded tire scrap decomposes into increasing amounts of gases and oil; and above 750ºF, oil and solid char yields can decrease relative to gas production. At these higher temperatures both the gases and oil produced are high in carcinogenic polycyclic aromatic...
