Abstract: In this paper, the surface reaction of NO thermal desorption and NO-CH4 reaction activity over Co-MgO catalyst were investigated. The adsorpted NO undergoes extensive decomposition to form N2 and N2O. There are two N2 peaks which are attributed to N(a) +NO (a) →N2+O(a) and 2N(a)→N2 reactions, respectively. There is only one N2O peak which is attributed to N(a) +NO (a)→N2O reaction. Because the O(a) produced during NO decomposition remains on Co microcrystallites, no O2 peak is observed. The ratio of CO2 and N2 in the products is near 1/2, which indicates that the reaction can be described as 4NO+CH4→2N2+CO2+H2O.

Key words: NO, temperature programmed surface reaction, NO-CH4 reaction, Co-MgO
