21. Software Package to Facilitate the Preparation of Intermediate-Range Fossil Fuel Standards from Certified Reference Materials
Topic: Fossil Fuels
Published: 6/17/2010
Authors: John L Molloy, Bruce S MacDonald, William R. Kelly
Abstract: A software package has been developed in Visual Basic for Applications to assist analysts in mixing fossil fuel reference materials to produce standards of intermediate concentrations and known uncertainties. Mixing reference materials of similar ma ...

22. Surrogate Mixture Models for the Thermophysical Properties of Aviation Fuel Jet-A
Topic: Fossil Fuels
Published: 5/27/2010
Authors: Marcia L Huber, Eric W Lemmon, Thomas J Bruno
Abstract: We developed surrogate mixture models to represent the thermophysical properties of two samples of aviation turbine fuel Jet-A. One sample is a composite of numerous batches from a multiple manufacturers and is considered to be a representative fuel ...

23. Investigating the Unique Properties of Cuphea Derived Biodiesel with the Advanced Distillation Curve Method
Topic: Fossil Fuels
Published: 5/17/2010
Authors: Tara M Lovestead, Bret Windom, Thomas J Bruno
Abstract: Currently, there is a desire to extend or enhance petroleum-derived diesel fuel with biodiesel fuel. Biodiesel fuel is a renewable, biomass-derived fluid that is biodegradable, nontoxic, and a better lubricant compared to petroleum-derived diesel fu ...

24. Assessment of the Compositional Variability of RP-1 and RP-2 with the Advanced Distillation Curve Approach
Topic: Fossil Fuels
Published: 5/7/2010
Authors: Bret Windom, Tara M Lovestead, Jennifer Riggs, Chris Nickell, Thomas J Bruno
Abstract: RP-1 is a long-established hydrocarbon fuel that continues to be widely used as the kerosene component in rocket propulsion systems. The desire in recent years to use rocket motors many times, rather than a single time, has led to reformulations of ...

25. Thermal Decomposition of RP-2 with Stabilizing Additives
Topic: Fossil Fuels
Published: 5/7/2010
Authors: Jason A Widegren, Thomas J Bruno
Abstract: The thermal decomposition of RP-2 and mixtures of RP-2 with four different additives has been investigated. The mixtures with RP-2 contained one of the following: 5 % /trans/-decahydronaphthalene (decalin); 5 % 1,2,3,4-tetrahydronaphthalene (tetralin ...

26. Application of the Advanced Distillation Curve Method to the Development of Unleaded Aviation Gasoline
Topic: Fossil Fuels
Published: 4/2/2010
Authors: Bret Windom, Tara M Lovestead, Thomas J Bruno
Abstract: The primary fuel used within the general aviation industry is a petroleum based gasoline blended with small amounts of tetraethyl lead (a lead-based additive used to increase the octane number of gasoline without affecting its performance) called 100 ...

27. Relating Complex Fluid Composition and Thermophysical Properties with the Advanced Distillation Curve Approach
Topic: Fossil Fuels
Published: 3/17/2010
Authors: Thomas J Bruno, Lisa S. Ott, Tara M Lovestead, Marcia L Huber
Abstract: Complex fluids have long posed a significant challenge in our ability to characterize and model fluid properties. Here, we consider complex fluids to be mixtures with many components that can differ significantly in polarity and polarizability. The ...

28. Complex Fluid Analysis with the Advanced Distillation Curve Approach
Topic: Fossil Fuels
Published: 2/1/2010
Authors: Thomas J Bruno, Lisa S. Ott, Beverly L. Smith, Tara M Lovestead
Abstract: An improved method for measuring distillation curves reveals the physicochemical properties of complex fluids such as fuels.

29. Density and Speed of Sound Measurements of Hexadecane
Topic: Fossil Fuels
Published: 1/7/2010
Authors: Stephanie L Outcalt, Arno R Laesecke, Tara J Fortin
Abstract: The density and speed of sound of hexadecane have been measured using two instruments. Both instruments use the vibrating-tube method for measuring density. Ambient pressure (83 kPa) density and speed of sound measurements were carried out with a r ...

30. Thermodynamic Properties of Propane. III. A Reference Equation of State for Temperatures from the Melting Line to 650 K and Pressures up to 1000 MPa
Topic: Fossil Fuels
Published: 11/23/2009
Authors: Eric W Lemmon, Mark O McLinden, W Wagner
Abstract: Times New RomanA formulation is presented for the thermodynamic properties of propane. The equation of state is valid for temperatures from the triple point temperature (85.525 K) to 650 K and for pressures up to 1000 MPa. The formulation can be us ...
