50/50 F-76/DSH-76 Specification and Fit-for-Purpose Level I Test Results

Abstract : Direct sugar to hydrocarbon diesel (DSH-76) is an iso-paraffinic single molecule fuel produced from direct fermentation of renewable sugars. This test report summarizes chemical, physical and fit for purpose (FFP) test results of a 70/30 and 50/50 blend of petroleum F-76 and DSH-76. The 70/30 and 50/50 F76/DSH-76 met all specification properties as set forth by MIL-DTL-16884L and FFP criteria as set forth by NAVSEA technical warrant holders, engine OEMs and subject matter experts1. Chemical profiling showed the chemical composition of neat DSH-76 to consist of a C15 iso-paraffinic molecule with very little side products. These test results support the continued qualification of 50/50 F76/DSH-76 for shipboard use by the U.S. Navy.
