Ev. Rebrov et al., Dinitrogen formation over low-exchanged Cu-ZSM-5 in the selective reduction of NO by propane, CATAL LETT, 58(2-3), 1999, pp. 107-118
The role of gaseous NO and C3H8 has been studied over low-exchanged Cu-ZSM-
5 zeolite employing TPD, FTIR and pulse technique with the alternate introd
uction of NO or C3H8 onto the catalyst surface. The rate of the N-2 formati
on is directly proportional to the content of gaseous NO and the surface co
verage with 2-nitrosopropane. There was no formation of N-2 during interact
ion of gaseous C3H8 with NO adsorbates. However, 2-nitrosopropane and its i
somer acetone oxime were also formed in this reaction.
