  • Patent number: 9422494
    Abstract: The present invention provides a process for producing jet fuel components from syngas. Syngas is converted to methanol and ethanol, and, optionally, higher alcohols. The methanol is separated from the ethanol and higher alcohols, and converted to C5-9 paraffins and aromatics via a dimethyl ether intermediate. The dimethyl ether is reacted over a catalyst to form jet fuel range hydrocarbons and aromatics. The ethanol and higher alcohols are dehydrated to form olefins, which are then oligomerized and, optionally, hydrogenated and/or isomerized, to form products in the jet fuel range. All or part of the two separate product streams can be combined, to provide jet fuel components which include aromatics and paraffins, ideally isoparaffins, in the jet fuel range. The syngas is in one embodiment derived from biomass or another renewable carbon-containing feedstock, thereby providing a biorefining process for producing renewable jet fuel.

  • Patent number: 8597497
    Abstract: A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feed comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen and at least one catalyst to produce a hydrocarbon-containing product. The hydrocarbon-containing feedstock, the catalyst(s), and the hydrogen are provided to a mixing zone and blended in the mixing zone at a temperature of from 375° C. to 500° C. A vapor comprised of hydrocarbons that are vaporizable at the temperature and pressure within the mixing zone is separated from the mixing zone, and, apart from the mixing zone, the vapor is condensed to produce a liquid hydrocarbon-containing product containing at least 85% of the atomic carbon initially present in the hydrocarbon-containing feedstock and containing at most 2 wt. % hydrocarbons having a boiling point of at least 538° C.
