Abstract
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 lo w-temperature range. These materials perform also impressively in the prese nce of 4% H2O in the feed stream, where a N-2 selectivity of 98% and an exc ellent stability over 24 h on stream have been observed. The MANPO material s can be considered serious competitors of noble metals for low-temperature "lean-deNO(x) applications.
