Abstract
The reaction of NO with adsorbed acetone oxime has been studied over Cu/ZSM-5 employing FTIR and MS. It is found that15NOgas reacts with14N labelled acetone oxime and/or its hydrolysis product, hydroxylamine, to form14N15NO and14N15N at 40°C. As acetone oxime is easily formed from alkyl radicals and NO via alkylnitroso compounds, the results indicate possible reaction paths for the SCR of NO x by hydrocarbons over zeolite based catalysts. The isotopic data suggest predominant formation of N-N bonds occurs via interaction of gaseous NO with a nitrogen containing adsorbed complex.
