Process for selectively producing high octane naphtha

A process for forming a high octane naphtha comprising:

• contacting a naphtha feed having a feed RVP, and a boiling range from about 65° F. to about 450° F., and an average feed octane number and containing paraffinic species and olefinic species under catalytic conversion conditions with a catalytically effective amount of a catalyst containing above 10 to 80 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nm at a temperature ranging from about 500° C. to about 650° C., a hydrocarbon partial pressure ranging from about 10 to about 40 psia, a hydrocarbon residence time ranging from about 1 to about 10 seconds, and a catalyst to feed weight ratio ranging from about 2 to about 10 in order to form the high octane naphtha having a product RVP substantially the same as or less than the feed RVP and wherein the resulting product contains from about 60 wt. % to about 90 wt. % less olefin than the naphtha feed.
