Abstract:

This report discusses the results of specification and fit-for-purpose testing of a 9010 blend of petroleum JP-5 and synthesized isoparaffins SIP, referred to as 9010 JP5SIP. SIP is produced by direct fermentation of sugar into olefinic hydrocarbons. The olefinic hydrocarbons are hydroprocessed to produce an iso-paraffinic hydrocarbon. To represent this class of renewable jet fuel, the Navy received SIP that was 98 pure branched paraffin with a fifteen carbon chain called 2,6,10 trimethyldodecane or farnesane. This fuel was unique because it was a single molecule unlike petroleum or Hydroprocessed Esters and Fatty Acids HEFA fuels, also called Hydroprocessed Renewable Jet fuels HRJ-5 , that have a broad range of different normal and iso-paraffins. The 9010 JP5SIP met all specification properties as set forth by MIL-DTL-5624V. This blend also passed all FFP Level I criteria, with the exception of viscosity at -40 deg C, set forth by in the Navy Standard Work Package 44FL-006 Naval Fuels and Lubricants CFT Shipboard Aviation Fuel, JP-54. Since the blend is 90 petroleum JP-5, the -40 deg C viscosity result is highly dependent on the viscosity of the JP-5 used to make the blend. Recent JP-5 viscosities at -40 deg C have ranged from 11.0-14.6 cSt based on data from the Navy sampling and World Fuel Sampling Program. For incorporation into the JP-5 specification, the blend ratio may be adjusted to ensure the viscosity is within historical JP-5 experience. The 9010 JP5SIP blend also passed select FFP Level II acceptance criteria that were covered in this report.
