Reaction of No and N2O Gases with Graphite in TGA

Korean Journal of Chemical Engineering, Vol.15, No.3, 336-340, May, 1998

Thermal analyses were conducted in a thermogravimetric analyzer by isothermal techniques in order to characterize the carbon-nitrogen oxide reaction. The carbon samples employed in the present study were SP-1 graphite and Micro 450 graphite. Carbon-NO and carbon-N₂O reactions were carried out in a temperature range of 550-900℃ and 5-20 kPa of the partial pressure of reactant. In the NO reaction, reaction orders with respect to NO concentration and activation energy were 0.46-0.92 and 85-102 kJ/mol, respectively. The rate on the monolayer edge was higher than the rate on the multilayer edges. In the N₂O reaction, reaction orders with respect to N₂O concentration and activation energy were 0.55-1.35 and 167-190 kJ/mol, respectively.
