Abstract
Abstract A process and a catalyst composition to effect hydrocarbon transformations comprising contacting a hydrocarbon charge with a catalyst comprising a fluorinated graphite having a fluorine to carbon atomic ratio of from about 0.1 to 1 and having bonded thereto from about 5 to 50 percent by weight of the total weight of the catalyst of at least one Lewis acid compound selected from halides of the elements of Group IIA, IIIA, IVB, V or VIB of the Periodic Table. In addition, the catalysts may also have bonded thereto a minor portion of a Bronsted acid and/or a metal of Group IVB or VIII of the Periodic Table.
