Abstract
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.
