Studies from National Institute of Standards and Technology in the Area of Fuel Research Described

June 27, 2014



By a News Reporter-Staff News Editor at Energy Weekly News -- Current study results on Fuel Research have been published. According to news originating from Boulder, Colorado, by VerticalNews correspondents, research stated, "Second-generation renewable fuels are synthesized through biochemical and thermochemical processes from nonfood biomass feedstock. The resultant fuels are similar to aliphatic synthetic fuels produced through the Fischer-Tropsch process, which contain mainly linear and lightly branched alkanes."

Our news journalists obtained a quote from the research from the National Institute of Standards and Technology, "We applied the advanced distillation curve method to an algae-based hydrotreated renewable naval distillate fuel (HRD-76) to measure its boiling temperature as a function of distillate volume fraction. Analysis of the bulk fuel sample through nuclear magnetic resonance spectroscopy, gas chromatography, and mass spectrometry showed the principal components to be linear and branched alkanes containing 14-18 carbon atoms. The speed of sound and density of the fuel were estimated from its composition and compared with experimental data measured with a density and sound speed analyzer. The estimates were within 5% of the experimental values. The boiling temperature, density, and composition data were used to estimate the calculated cetane index of the fuel. We also measured the cloud point of the fuel through a constant cooling rate method with optical detection of paraffin wax precipitation. The measured cloud point was consistent with reported values for hydrotreated renewable fuels, which tend to be higher than cloud points of diesel fuels derived from petroleum."

According to the news editors, the research concluded: "The quantitative thermophysical and chemical data can be used to improve combustion modeling of HRD-76 and other second-generation renewable fuels."
