ABSTRACT:
A process combination is disclosed to selectively upgrade naphtha to obtain an isoparaffin-rich product for blending into gasoline. A naphtha feedstock is subjected to ring cleavage to convert naphthenes to paraffins using a nonacidic catalyst followed by isomerization of paraffins to obtain an increased proportion of isoparaffins. Ring cleavage also may be effected on the product of isomerization and separation by fractionation or adsorption.
