Abstract
A process for producing a high RON naphtha which comprises contacting a hydrocarbon feed stream comprising a mixture of the isomers of Cand Cparaffins with ATS zeolite, such as SSZ-55, in an adsorption zone, whereby the branched isomers of the Cand Cparaffins are preferentially adsorbed by the ATS zeolite as compared to the straight chain isomers, and recovering a naphtha product from the adsorption zone having a higher RON than the hydrocarbon feed stream, also including a hydroisomerization process and a hydrocracking process.
