ABSTRACT:
A reactivation process is disclosed for a catalyst formulated to selectively upgrade naphtha to obtain an isoparaffin-rich product for blending into gasoline. The process utilizes a solid strong-acid catalyst comprising an anion-modified metal oxide, preferably comprising a sulfated support of an oxide or hydroxide of a Group IVB (IUPAC 4) metal, and a platinum-group metal component.
