Effect of pore structure and surface chemical properties of activated carbon on the adsorption and oxidation of NO |
| |
| Abstract: | Five kinds of powder activated carbons were investigated to the adsorption and oxidation of NO at low temperature in a batch fluidized bed reactor.The adsorbents were characterized by N 2 adsorption,elemental analysis,Boehm titration and pH measurement.The activated carbons have different pore structure and surface chemical properties because of the different precursor and activation method,and present different time course of adsorption and oxidation of NO.NO conversion into NO 2 in the stationary stage is correlated with the properties of activated carbons.The results show that NO conversion is independent of the pore structure such as specific surface area,pore volume,and average pore width.NO conversion increases with the amounts of surface basic functional groups.The surface chemistry is the most important factor on the adsorption and oxidation of NO for the samples used in this study. |
