Abstract
The present invention relates to new crystalline molecular sieve SSZ-74 prepared using a hexamethylene-1,6-bis-(N-methyl-N-pyrrolidinium)dication 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.
