| 摘要 |
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, methods for synthesizing SSZ-74, and its use in hydrocarbon conversion reactions, reduction of oxides of 5 nitrogen in a gas stream, partial oxidation reactions, acylation reactions, oxygenate conversions, gas separations, synthesis of amines, treatment of engine exhaust (reduction of cold start emissions), and Beckmann rearrangement. |
