“…The research group report that experiments on a small scale fixed bed reactor produced oil yields of 56.4 wt%, the difference compared to the moving bed screw reactor were attributed to the differences in heating rate and gas residence times between the two reactors (Aylón et al 2008). Diez et al (2005) also used a screw kiln reactor, externally heated by an electrical furnace to investigate the pyrolysis of shredded tyre at a pyrolysis temperature of 500/600°C.…”

Approximately 1.5 billion tyres are produced each year which will eventually enter the waste stream representing a major potential waste and environmental problem. However, there is growing interest in pyrolysis as a technology to treat tyres to produce valuable oil, char and gas products. The most common reactors used are fixed-bed (batch), screw kiln, rotary kiln, vacuum and fluidised-bed. The key influence on the product yield, and gas and oil composition, is the type of reactor used which in turn determines the temperature and heating rate. Tyre pyrolysis oil is chemically very complex containing aliphatic, aromatic, heteroatom and polar fractions. The fuel characteristics of the tyre oil shows that it is similar to a gas oil or light fuel oil and has been successfully combusted in test furnaces and engines. The main gases produced from the pyrolysis of waste tyres are H 2 , C 1 -C 4 hydrocarbons, CO 2 , CO and H 2 S. Upgrading tyre pyrolysis products to high value products has concentrated on char upgrading to higher quality carbon black and to activated carbon. The use of catalysts to upgrade the oil to a aromatic-rich chemical feedstock or the production of hydrogen from waste tyres has also been reported. Examples of commercial and semi-commercial scale tyre pyrolysis systems show that small scale batch reactors and continuous rotary kiln reactors have been developed to commercial scale.
