Improvement of the thermal durability of the SCR catalysts would therefore be the key to maximizing the fuel efficiency, as well as to producing clean emissions from diesel engines. The feed contains 500 ppm NH 3 , 500 ppm NO, 5% O 2 , 10% H 2 O balanced with N 2 at 100,000 h -1 gas hourly space velocity. —Ryu et al.
