  • Patent number: 7776207
    Abstract: A process for producing alkyl aromatic middle distillate fuels is described. The process includes (a) catalytically converting paraffinic naphtha to a composition containing benzene and olefins; (b) processing the olefin/benzene composition in an aromatic alkylation reactor to produce alkyl-benzene components (c) separating the alkyl aromatics from the unconverted naphtha; and (d) optionally recycling the unconverted paraffinic naphtha to the dehydrogenation/amortization reactor of step a.
    Type: Grant
    Filed: October 5, 2007
    Date of Patent: August 17, 2010
    Assignee: Syntroleum Corporation
    Inventors: Ramin Abhari, Paul Ahner
