  • Process for co-producing jet fuel and LPG from renewable sources
    Patent number: 7846323
    Abstract: The present invention generally relates to a method for producing an isoparaffinic product useful as jet fuel from a renewable feedstock. The method may also include co-producing a jet fuel and a liquefied petroleum gas (LPG) fraction from a renewable feedstock. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins and hydroisomerizing the hydrotreating unit heavy fraction to produce a hydroizomerizing unit heavy fraction that includes isoparaffins. The method also includes recycling the hydroisomerizing unit heavy fraction through the hydroisomerization unit to produce an isoparaffinic product that may be fractionated into a jet fuel and an LPG fraction. The present invention also relates to a jet fuel produced from a renewable feedstock having improved cold flow properties.
