Little, beyond crude assay data, has been known about the properties of various fuel fractions, including diesel fuel, which might ensue in the event crude oils available at the Strategic Petroleum Reserve were actually to be refined. Accordingly, eight distinct crude oil streams were collected from the Reserve and subjected to distillation in a pilot-scale unit. Middle distillate fractions were prepared in an attempt to approximate production of diesel fuel, and the fractions were characterized by ASTM tests and evaluated according to the requirements of VV-F-800 and other criteria. VV-F-800 is the Federal Diesel Fuel Specification. Results of the distillation effort were documented and indicate a successful effort over the range of operating conditions explored. The diesel fuels produced exhibit cetane numbers greater than specification requirements and can be expected to be stable. The data indicate that fuels conforming to VV-F-800 can be obtained from Strategic Petroleum Reserve crude oil, although a normal amount of additional upgrading may be required. Recommendations are made to examine such upgraded material, including full-scale engine testing, to demonstrate the power and performance of both treated and untreated fuels.
