Abstract: A rocket propellant includes a hydrocarbon blend having a total aromatic compounds content less than 0.5 mass percent, a specific energy of at least 18.4 KBtu/lb, and a mass density of at least 0.8150 grams per cubic centimeter. The propellant, which can be prepared by blending a refined kerosene with an isoparaffin and/or a cycloparaffin, exhibits a high volumetric heat of combustion and excellent thermal stability. This combination of properties is especially useful for fueling reusable launch vehicles employing regenerative cooling of engine components.

Abstract: A process for preparing an E10 test fuel in accordance with 40 CFR 1065.710(b) includes steps of combining an aromatic pre-blend having an aromatic distribution in accordance with 40 CFR 1065.710(b), or a combination of aromatic blendstocks that if combined into a mixture would have an aromatic distribution in accordance with 40 CFR 1065.710(b), with at least one paraffinic refining blendstock, and optionally adding ethanol, butane, olefin-containing blendstocks, sulfur compounds or sulfur-containing blendstocks as needed to meet the requirements of 40 CFR 1065.710(b).

Abstract: A process for isomerizing endo-hydrogenated dicyclopentadiene to form the corresponding exo-isomer using a stable, pumpable liquid aluminum halide catalyst which includes steps of providing a first solution containing a hydrogenated dicyclopentadiene compound that is dissolved in a hydrocarbon solvent, adding a cosolvent to the first solution to form a second solution, adding an aluminum halide to the second solution, and isomerizing the hydrogenated dicyclopentadiene compound in the presence of dissolved aluminum halide which acts as a catalyst to produce the corresponding exo-isomer.

Abstract: Disclosed is a process of fueling a rocket engine or air-breathing engine for a hypersonic vehicle with a high performance hydrocarbon fuel characterized by a hydrogen content greater than 14.3% by weight, a hydrogen to carbon atomic ratio greater than 2.0 and/or a heat of combustion greater than 18.7 KBtu/lb. The disclosed fuels generally have a paraffin content that is at least 90% by mass and a C12-C20 isoparaffin content of at least 40% by mass.

Abstract: A composition useful as a Reference Standard for measurement of Cetane Number or for use as a standard for determining a Derived Cetane Number consists essentially of a blend of n-hexadecane and 2,2,4,6,6-pentamethylheptane. The disclosed Reference Standards can be used directly as substitutes for blends of n-hexadecane and 2,2,4,4,6,8,8-heptamethylnonane in ASTM D613-10a for determining Cetane Number, or in ASTM D6890, ASTM D7170 or ASTM D7668 to determine a Derived Cetane Number.

Abstract: A high octane non-leaded gasoline meeting ASTM D910 LL standard is provided that includes a base gasoline fuel having a minimum MON of 96.5 and meeting the ASTM D910 standard. An octane-boosting component is mixed with the base gasoline fuel that raises the MON above 99.6 and the blended fuel complies with ASTM D910. The octane-boosting component is selected from a group including an additive, TEL only and a TEL containing gasoline.
