  • Method for improving the long-term color stability of jet fuel
    Patent number: H1368
    Abstract: A method for improving the long-term color stability of jet fuel and jet fuel blends containing nitrogen compounds, by intimately mixing the jet fuel with a quantity of concentrated sulfuric acid sufficient to remove at least about ninety percent (90%) of said nitrogen compounds during a contact time equal to less than five (5) minutes, separating the jet fuel from the concentrated sulfuric acid, mixing the jet fuel with an aqueous caustic solution to remove residual acid from the jet fuel, separating the jet fuel from the aqueous caustic solution, mixing the jet fuel with water, and separating the jet fuel from the water.
