ABSTRACT:
Low-octane C.sub.5 -C.sub.6 gasoline pool mixtures or components are upgraded into improved-octane gasoline blendstock by (1) catalytically converting a minor yet significant portion of the C.sub.6 -fraction into a relatively high-octane stock using a unique crystalline aluminosilica zeolite catalyst, (2) isomerizing the C.sub.5 -fraction plus the remainder of the C.sub.6 -fraction, and (3) blending the converted C.sub.6 -portion with the C.sub.5 -C.sub.6 isomerizate.
