ABSTRACT:
The present invention relates to new crystalline, essentially all silicon oxide molecular sieve SSZ-73 prepared using a 3-ethyl-1,3,8,8-tetramethyl-3-azoniabicyclo[3.2.1]octane cation as a structure-directing agent, and its use in the reduction of oxides of nitrogen in a gas stream such as the exhaust from an internal combustion engine.
