The CH4/NO/O-2 "lean-deNO(x)" reaction on mesoporous Mn-based mixed oxides (Journal article)

Stathopoulos, V. N./ Costa, C. N./ Pomonis, P. J./ Efstathiou, A. M.

High surface area Mn-based porous oxides (MANPO) containing additives like Ce, Sr and La were found to be very active and selective materials under 0.67% CH4/0.2% NO/5% O-2 "lean-deNO(x)" conditions in the 200-300 degreesC low-temperature range. These materials perform also impressively in the presence of 4% H2O in the feed stream, where a N-2 selectivity of 98% and an excellent stability over 24 h on stream have been observed. The MANPO materials can be considered serious competitors of noble metals for low-temperature "lean-deNO(x) applications.
