  • ISOMERIZATION OF LIGHT PARAFFINS
    Publication number: 20130165714
    Abstract: A process for isomerizing light paraffins using a catalyst comprising an *SFV-type zeolite and at least one Group VIII metal. It has been found that the catalyst can selectively convert C6 paraffins into the more favorable higher octane C6 isomer, namely 2,3-dimethylbutane (RON=105), over the less favorable C6 isomer, namely octane 2,2-dimethylbutane (RON=94).
    Type: Application
    Filed: December 21, 2011
    Publication date: June 27, 2013
    Applicant: Chevron U.S.A. Inc.
