    Abstract

    The rate of reaction of nitromethane in the gas phase is little changed by the presence of O2 or NO. The major products are CO, NO and H2O, plus NO2 if O2 is included. The corresponding catalytic reaction over fresh Co-ZSM5 commences at a much lower temperature and gives primarily CO2 and NH3. the latter being oxidised to N2 above 340°C. As the catalyst ages below 320°C HNCO eventually becomes the major nitrogen-containing product although it can be hydrolysed by added water. The results demonstrate one possible route for the methane-SCR reaction.
