The possibility of forming nitrogen in the gas phase by reaction of activated forms of NO x with amines and ammonia as well as with other organic intermediates, which can be converted to amines and/or ammonia, was investigated. The activation of NO was carried out by passing NO together with oxygen and small amounts of hydrogen over an Ag/alumina catalyst. A special T-shaped reactor was used...
An Ag/alumina catalyst was prepared and tested for its HC(octane)-SCR activity using a gas mixture simulating exhaust gas from diesel and lean-burn vehicles. The catalyst showed excellent NO to N 2 activity, having a maximum conversion of approximately 90% at 450°C and an average conversion of 66% in the temperature window 300–600°C. During the high conversion of NO, formation of CO was recorded...
