Differences Between Al2O3 and Ag/Al2O3 for Lean Reduction of NOx with Dimethyl Ether
Journal article, 2009

Lean reduction of NOx with DME occurs with high selectivity to N-2 over Al2O3 between 300 degrees C and 550 degrees C with a maximum of 47% at 380 degrees C, and with lower selectivity over Ag/Al2O3 between 250 degrees C and 400 degrees C due to the catalysts' sensitivity to gas phase radical reactions and activity for NOx reduction with methanol.
