  • Process for paraffin hydrocarbon isomerization and composite catalyst therefore
    Patent number: 7053261
    Abstract: A process for the conversion of linear and/or branched paraffin hydrocarbons based on the use of an ionic liquid catalyst in combination with a metal salt additive, which provides a catalytic composition with an increased activity, compared with said ionic liquid. Under suitable reaction conditions this conversion is leading to paraffin hydrocarbon fraction with higher octane number.
    Type: Grant
    Filed: March 14, 2003
    Date of Patent: May 30, 2006
    Assignee: Haldor Topsoe A/S
    Inventors: Konrad Herbst, Jindrich Houzvicka, Birgitte Tofte Jespersen, John Zavilla
