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 tungstated oxide or hydroxide of a Group IVB (IUPAC 4) metal, a phosphorus component, and at least one platinum-group metal component which is preferably platinum. The catalyst has a structure other than a hetropoly anion structure.
