  • Patent number: 10065900
    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.

  • Patent number: 9567270
    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.
