ABSTRACT:
Hydrocarbon conversion processes are disclosed which are catalyzed by novel pillared clay compositions. The clay contains pillars which are at least partially fluorided. These pillars are metal fluoro hydroxy cations where the metal can be Al, Zr, Si/Al, Ti or Cr. The clays which can be pillared with these pillars are the smectite clays which include hectorite and beidellite along with synthetically prepared smectite clays. These clays are prepared by pillaring the clay, followed by calcination and then treatment with a fluoride salt such as ammonium bifluoride.
