(ZSM-5) Catalytic pyrolysis of tires: influence of catalyst temperature. Two stage pyrolysis–catalysis of used tires was undertaken to upgrade the derived oil to a highly aromatic oil suitable to be used as a chemical feedstock rather than a liquid fuel.
The tires were pyrolyzed in a fixed bed reactor and the evolved pyrolysis gases were passed through a secondary fixed bed reactor containing zeolite catalyst. The pyrolysis reactor was maintained at 500 °C and the influence of catalyst temperature between 430 and 600 °C on the yield and composition of the derived oils was examined.
