摘要： 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).
