The road to Sustainable Aviation Fuels

While all Sustainable Aviation Fuels are designed to be drop-in jet fuels – meaning that their chemical compositions are similar to those of conventional fossil-based fuels, some additional requirements are necessary to ensure that they are strictly regulated and fit for purpose. 

ASTM D7566 vs ASTM D1655

Current commercial-scale producers opt for the HEFA production pathway defined in ASTM D7566. This process uses hydrogenation, cracking and isomerization to convert vegetable oils, waste oils and residue fats into jet-fuel like molecules. It does however come with its challenges, where unconverted esters and fatty acids can impact critical parameters such as thermal stability, low temperature viscosity or freezing point.

Another approved pathway is co-processing defined in ASTM D1655 and Def Stan 91-091, where the same raw bio-ingredients are processed along with conventional crude oils. 

JFA-70Xi for Sustainable Aviation Fuel

Enter Phase Technology’s JFA-70Xi analyzer – a game changer in the realm of Jet Fuel testing. 

Tailored specifically for the Jet Fuel industry, this 3-in-1 analyzer offers a comprehensive solution for measuring Freezing Point, Kinematic Viscosity at -20°C/-40°C, sample temperature at 12cSt and Density.

To save valuable space in the lab, the JFA-70Xi is equipped with an integrated cooling system that avoids the use of a bulky cryostat. A graphical representation of the cooling cycle during a test allows to capture any contamination of the sample that will change the freezing point.
While both the instrument and its test methods have been approved in aforementioned norms, the key advantage is the ability to deliver a precise result of the three critical parameters within 15 minutes.

In an industry where safety and performance are non-negotiable, the JFA-70Xi empowers you to make informed decisions with confidence, assess critical parameters and therefore streamlining your processes.
