The liquid fuel produced by thermodynamically cracking suitable feedstock is a synthetic diesel/gasoil which has proven to be suitable for power generation in standard diesel/gasoil engines. Because of the fuel’s origins, it cannot (by definition) be classified as a petro (or fossil) fuel, and so there are no appropriate synthetic standards to measure the specification against – consequently it can only be compared with similar current petrodiesel/gasoil standards.
Whilst each feedstock is different, the cracking process produces liquid fuels which are remarkably consistent. A typical analysis of the oil produced is shown in the download tab below.
The liquid fuel produced does not directly fit all the required physical characteristics of EN590 petrodiesel for automotive applications; or EN14214 FAME biodiesel for automotive applications; or BS2869 middle distillate fuels class D for stationary applications – although it does have some properties of each. It does however conform to the standard for BS2869 class E – residue containing burner fuels. The fuel produced by the TDR process has the key physical characteristics of:
- Gross calorific value of 10,400 Kcal/kg – in line with petrodiesel.
- Density of 0.85 – 0.87 kg/m³ – in line with petrodiesel.
- The distillation curve shows that the liquid is classified as ‘light’.
- Kinematic viscosity is below 3 mm²/s – in line with petrodiesel.
- Sulphur content – is dependent upon the feedstock but is lower than 1% (5,000 ppm) – current petrodiesel/gasoil specifications now set a maximum level of 0.01% (100 ppm) for automotive, 0.1% for BS2869 Class D, and 1.0% for BS2869 Class E residue burner fuel.
- Flashpoint – can be set according to customer preference but would be nominally be at least 55°C to allow for convenient storage, a flashpoint of 66°C can also be produced to conform with the specification for BS2869 Class E fuels.
Feedstock materials with low sulphur composition will enable the higher grade of BS2869 Class D to be reached.
