  • Process for reforming nephthene and paraffin-containing hydrocarbons in the naphtha boiling range and isomerizing C5-C6 normal paraffin feedstock to produce a high octane gasoline
    Patent number: 4923589
    Abstract: A combined reforming and isomerization process wherein at least a portion of the hydrogen produced in the reforming process is passed with a C.sub.5 -C.sub.6 range normal paraffin feedstock to an isomerization zone, containing an isomerization catalyst, at isomerization condition to produce an isomerized C.sub.5 -C.sub.6 product stream and passing the C.sub.5 -C.sub.6 isomerized product stream to a reformate separation zone (hydrogen stripping and topping zones) and recovering at least a major portion of the isomerized C.sub.5 -C.sub.5 product stream with the reformate for use as a high octane gasoline product.
