ABSTRACT:
The invention relates to the production of high octane fuels including a process for separating the high octane components for the gasoline pool from lower octane components, which are recycled to an isomerization reaction by adsorptively separating dimethyl paraffins from an isomerate with an aluminophosphate zeolite and SSZ-24, an all-silica zeolite adsorbent isostructural with AIPO.sub.4 -5, and a C.sub.6-10 normal paraffin desorbent. The lower octane components of the isomerate, normal paraffins and mono-branched paraffins, are recycled to the isomerization reaction zone for further conversion to multi-branched paraffins. The useful aluminophosphates are SAPO-5, AIPO.sub.4 -5 MgAPO-5 and MAPSO-5.
