Definitions

  • the present invention relates to new crystalline molecular sieve SSZ-65, a method for preparing SSZ-65 using a l-[l-(4-chlorophenyl)-cyclopropylmethyl]-l- ethyl-pyrrolidinium or 1 -ethyl- l-(l-phenyl-cyclopropylmethyl)-pyrrolidinium cation as a structure directing agent and the use of SSZ-65 in catalysts for, e.g., hydrocarbon conversion reactions.
  • crystalline molecular sieves and molecular sieves are especially useful in applications such as hydrocarbon conversion, gas drying and separation. Although many different crystalline molecular sieves have been disclosed, there is a continuing need for new molecular sieves with desirable properties for gas separation and drying, hydrocarbon and chemical conversions, and other applications. New molecular sieves may contain novel internal pore architectures, providing enhanced selectivities in these processes. Crystalline aluminosilicates are usually prepared from aqueous reaction mixtures containing alkali or alkaline earth metal oxides, silica, and alumina.
  • Crystalline borosilicates are usually prepared under similar reaction conditions except that boron is used in place of aluminum. By varying the synthesis conditions and the composition of the reaction mixture, different molecular sieves can often be formed.
  • SSZ-65 a family of crystalline molecular sieves with unique properties, referred to herein as "molecular sieve SSZ-65" or simply "SSZ-65".
  • SSZ-65 is obtained in its silicate, aluminosilicate, titanosilicate, germanosilicate, vanadosilicate or borosilicate form.
  • silicate refers to a molecular sieve having a high mole ratio of silicon oxide relative to aluminum oxide, preferably a mole ratio greater than 100, including molecular sieves comprised entirely of silicon oxide.

For high catalytic activity, the SSZ-65 molecular sieve should be predominantly in its hydrogen ion form. It is preferred that, after calcination, at least 80% of the cation sites are occupied by hydrogen ions and/or rare earth ions.
