Study on kinetics of adsorption and oxidation of NO over powder activated carbon
Abstract：Kinetics of NO adsorption and oxidation over powder activated carbon at low temperature in a batch fluidized bed reactor was studied.The results show that when oxygen is present,activated carbon acts as an adsorbent and a catalyst for NO oxidation into NO2 and a stable NO conversion rate is achieved.Powder activated carbon presents higher activity of NO adsorption and oxidation than granular activated carbon.The NO conversion rate increases with O2 and NO concentration increasing.The apparent reaction order of NO oxidation in the stable stage for O2 varies from 0.9 to 0.2 and the apparent reaction order of NO oxidation in the stable stage for NO is 1.3.Adsorption and oxidation of NO over powder activated carbon includes the formation of（NO）2 and the disproportionation of NO2.
