  • Aviation fuel cold flow additives and compositions
    Publication number: 20040250468
    Abstract: Aviation fuel, such as jet fuel, blends and methods for improving cold flow properties of such fuels at extremely low temperatures are disclosed. Cold flow properties of, for example, JP-8 jet fuel are improved by addition to the fuel of an oil-soluble, polar nitrogen-containing compound. Demonstratable cold flow improvement of such fuels at temperatures of about −53° C. and lower is shown.

  • Control carbonyl concentration in diolefinic products using hydroxyamine sulfate as an extraction aid
    Publication number: 20020139710
    Abstract: The present invention is directed to the use of hydroxylamine, its acid salts or mixtures thereof to increase carbonyl extraction during the basic washing of hydrocarbons containing oxygenated compounds. More specifically, oxygenated compounds such as carbonyl containing organics are typically an impurity and have a tendency to polymerize, producing fouling elements during processing. The hydroxylamine and its salts are quite effective for increasing the extraction of the carbonyl impurities during the caustic washing of hydrocarbon streams.
