Upgrading of spent butane isomerization catalyst to pentane isomerization catalyst
A process is described for the isomerization of pentane to isopentane which comprises contacting a feed comprising normal-pentane under isomerization conditions with a catalyst prepared by (a) washing a chloride-containing platinum on alumina support isomerization catalyst with wash medium under conditions suitable to remove substantially all chloride ions; (b) treating the product of (a) with at least one aqueous fluorinating agent under conditions suitable to provide intimate contact between the alumina support and the fluorinating agent; and (c) drying the product of (b) under conditions suitable to produce a substantially water-free fluoride-containing platinum on alumina support isomerization catalyst.
