Abstract

The mechanism of the reaction of NO with carbon was examined, with a particular focus on the role of desorption of oxides from the surface. The carbon was an ex-phenol formaldehyde char of low impurity levels, the temperature range studied was 773-1073 K, and the partial pressure of NO was varied from 1 to 10.1 kPa. The reaction was characterized by two different mechanistic regimes. The low temperature regime (<923 K) was characterized by a non-constant activation energy in the range 63-88 kJ/mol, and the activation energy appears related to the activation energy distribution for desorption of surface oxides. The high temperature regime was governed by a product release step involving participation of NO, and exhibited by an activation energy of 180 kJ/mol. The desorption process was modeled using distributed activation energy kinetics.
