The pyrolytic oil fraction corresponding to the 150–370 °C is about 60 wt% of the total oils. In order to establish the real potential use of such tire oil fraction as diesel oil, a more thorough characterisation of it, which should include cetane index, corrosive properties, flash point, etc., is needed.

Abstract. The latest results and theories concerning both mechanistic and industrial aspects of pyrolysis reactions and processes are presented.
Yields of oil, char, and gas were 37–42.2 wt %, 41.7– 45.3 wt %, and 16–19.5 wt %, respectively. The characterization and potential application of py-rolytic gases and oils has been the subject of a number of publications. Pyrolytic oils, a mixture of paraffins, olefins, and aromatics, possess a high calorific value of 43 MJ/kg
pyrolysis oil is easily distillable fraction with boiling points between 70°C and 210°C, which is the boiling point range specified for commercial petrol. On the other hand, 75% of the pyrolytic oil has a boiling point under 370°C, which is the upper limit specified for 95% of distilled product of diesel oil.
the recovery of useful products, such as pyrolytic oil and pyrolytic carbon black (CBp). The light part of the pyrolytic oil contains dl-limonene which has a high price on the market. The naphtha fraction (initial boiling point (IBP) < 160ºC) can be used as a high octane number component for gasoline.

A sample size of 40 g waste tyre crumb was fed in the pyrolysis reactor.The preferred operational conditions, suitable for a maximum limonene yield in the TDO, were similar to those established from previous work, i.e., a final pyrolysis temperature of 475 °C, a heating rate of 20 °C/min, and a pyrolysis time of 60 min .The hot volatiles were purged out from the reactor with nitrogen gas …
At a pressure of 1.0 MPa, the yield of limonene increases by 20% as the residence time decreases from 60 s to 15 s, while limonene concentration in TDO (tire-derived-oil) increases to 35.10 wt.%.
