Abstract
An integrated process for the production of a refinery gasoline pool with enhanced octane value from a pentane and hexane containing feedstock by first contacting with an isomerization catalyst; fractionating the resulting product into an iC.sub.5 product stream forming part of said refinery gasoline pool and a bottom stream containing nC.sub.5, nC.sub.6, mono-branched C.sub.6 and dibranched C.sub.6 ; passing said bottom stream through an adsorption bed with dibranched C.sub.6 passing thru unabsorbed; desorbing nC.sub.5, nC.sub.6 and monobranched C.sub.6 from the absorption bed; and recycling the desorbed nC.sub.5, nC.sub.6 and monobranched C.sub.6 to the isomerization zone.
