ABSTRACT:
This invention relates to processes for separating by adsorption lower octane normal and mono-methyl paraffins from hydrocarbon feeds containing normal, mono-methyl and more highly branched paraffin fractions and isomerizing the normal and mono-methyl paraffins to produce higher octane isopentane and more highly branched paraffins. Adsorbents capable of adsorbing both normal and mono-methyl paraffins are used either alone or in combination with adsorbents capable of adsorbing normal paraffins but not mono-methyl paraffins. Isopentane, although adsorbed along with the mono-methyl paraffins, is preferentially eluted from the adsorber and recovered as an adsorption effluent.
