Abstract
Described herein is a new crystalline molecular sieve Al-SSZ-63 prepared by a direct synthesis. The synthesis uses N-cyclodecyl-N-methyl-pyrrolidinium cation as a structure-directing agent. A method for directly synthesizing the Al-SSZ-63 is also provided, as are processes employing the Al-SSZ-63 in a catalyst.
Claims15
A molecular sieve having a mole ratio greater than about 15 of (a) a silicon oxide obtained from fumed silica to (b) an aluminum oxide and having, after calcination, the X-ray diffraction lines of Table IV.
A method of preparing a crystalline material comprising (a) a silicon oxide and (b) an aluminum oxide having a mole ratio of the silicon oxide to the aluminum oxide greater than 15, said method comprising contacting under crystallization conditions sources of said oxides and a structure directing agent comprising a N-cyclodecyl-N-methyl-pyrrolidinium cation, wherein the source of the silicon oxide comprises fumed silica.
