ABSTRACT:
A catalyst and process is disclosed to selectively upgrade a paraffinic feedstock to obtain an isoparaffin-rich product for blending into gasoline. The catalyst comprises a support of a sulfated oxide or hydroxide of a Group IVB (IUPAC 4) metal, a first component comprising at least one Group III A (IUPAC 13) component, and at least one platinum-group metal component which is preferably platinum.
