    摘要： There is disclosed a method of making, through direct synthesis, a catalyst comprising an Fe-SAPO-34 molecular sieve. There is also disclosed an Fe-SAPO-34 molecular sieve made according to the disclosed method herein, wherein the molecular sieve contains both framework iron and iron cations at ion-exchange sites. In addition, there is disclosed a method of using the Fe-SAPO-34 disclosed herein in a selective catalytic reduction reaction, typically in the presence of ammonia or urea, to reduce or remove nitric oxides from exhaust emissions.

    摘要： There is disclosed a hydrothermally stable microporous crystalline material comprising a molecular sieve or zeolite having an 8-ring pore opening structure, such as SAPO-34 or aluminosilicate zeolite, able to retain a specific percentage of its surface area and micropore volume after treatment with heat and moisture, such as at least 80% of its surface area and micropore volume after exposure to temperatures of up to 900° C. in the presence of up to 10 volume percent water vapor for a time ranging from 1 to 16 hours. Methods of using the disclosed crystalline material, such as in the SCR of NOx in exhaust gas are also disclosed, as are methods of making such materials.
