Abstract:
In October 2009, Secretary of the Navy Ray Mabus directed the Navy to decrease its reliance on fossil fuels. The Secretary set a goal of operating with at least 50 of energy consumption coming from alternative sources by 2020. He also set forth the goal of demonstrating a Great Green Fleet, operating on 50 alternative fuel, by 2012 and deploying by 2016. The use of alternativepetroleum sourced aviation fuel blends is a critical component to achieving these goals. An alternative sourced fuel currently under-going qualification testing is a 9010 blend of petroleum JP-5 and Synthesized Iso-Paraffins SIP. SIP fuels are made from 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 a 98 pure branched paraffin with a fifteen carbon chain called 2,6,10 trimethyldodecane or farnesane. The 5050 F-76SIP fuel blends ability to coalesce free water was evaluated by performing a Navy Coalescence Test NCT. The NCT is a level II fit-for-purpose test which uses a specially manufactured scaled down filtercoalescer and separator to simulate the performance of a full-scale filter separator system. This test is designed to predict the performance of new additives and fuels on filter separator systems currently in use by the fleet.
