Abstract:
Catalysts comprising metal-loaded non-zeolitic molecular sieves having the CHA crystal structure, including Cu-SAPO-34, and methods for treating exhaust gas incorporating such catalysts are disclosed. The catalysts can be used to remove nitrogen oxides from a gaseous medium across a broad temperature range and exhibit hydrothermal stability at high reaction temperatures.

Claim (Index 20):
A catalyst comprising:\n an ion-exchanged Cu-SAPO-34 non-zeolitic molecular sieve having a CHA crystal structure; wherein the Cu content of the Cu-SAPO-34 non-zeolitic molecular sieve on a CuO basis is in the range of about 1% to about 5% by weight; wherein the Cu-SAPO-34 non-zeolitic molecular sieve has a BET surface area greater than 350 m 2 /g; wherein the catalyst is effective to promote the reaction of ammonia with nitrogen oxides (NOx) to form nitrogen and H 2 O selectively in an exhaust gas stream at 200\u00b0 C. when the catalyst has been deposited on a honeycomb substrate having a cell density of 400 cpsi at a loading between 2 and 2.5 g/in 3  and tested at a space velocity of 80,000 hr \u22121  where the feed stream comprises a mixture of 10% O 2 , 5% H 2 O, 500 ppm NO and 500 ppm NH 3  to provide at least 80% NOx conversion; and wherein the catalyst is effective to make less than 5 ppm N 2 O over a temperature range of 200\u00b0 C. to 450\u00b0 C.
