The pyrolysis process produces an oil product that is similar in viscosity to No.2 grade oil.

 

A smaller quantity of lighter grade oil is produced from gas condensers which remove residual oil from non‐condensable gases. Because of the relatively uneconomic process of de-sulphurising smaller quantities of oil, it is intended, in Phase 1, to use the combined oil, along with the gas, for steam‐turbine driven electricity generation, to maximise electricity sales and the related benefit of ROCs.

Study conducted by : ICI Measurement Science Group, Molecular Spectroscopy, D115, Wilton Centre, in 2007.

 

Summary
The sample contained a complex mixture of aliphatic and aromatic hydrocarbons.  The data indicate that it is similar in composition to many complex hydrocarbon feedstocks.  Many of the more volatile components (toluene and xylenes for example) could be extracted and used as solvents. 

 

Indeed, crude hydrocarbon feedstocks are used as solvents for some polymer systems (such as resins). 

Styrene, which is a significant component in the pyrolysate, can be used as a monomer to make poly(styrene).
