  • Method for preparing high energy fuels
    Patent number: 8450544
    Abstract: A method for preparing the low carbon number petrochemical products along with the high energy fuels from pyrolysis gasoline is provided. In this method, the pyrolysis gasoline is used as feedstock, and the reactive non-aromatic, unsaturated moieties, and the sulfur impurity contained in the pyrolysis gasoline are removed. Then the stabilized feedstock is used to produce C5 olefins, C6-C9 aromatic hydrocarbons as petrochemical products, and C10+ hydrocarbons as precursors of high energy fuels. Upon acid catalytic isomerization, or upon crystallization followed by acid catalytic isomerization, the C10+ hydrocarbons as precursors of high energy fuels are converted to exo-isomers as high energy fuels.
    Type: Grant
