초록

The objective of this study was to assess the catalytic activities of manganese oxide (MnO, $MnO_2$, $Mn_2O_3$, and $Mn_3O_4$) catalysts for odors (acetaldehyde and propionaldehyde) removal. We used a fixed bed reactor as the experimental apparatus and the catalytic performance were carried out over the temperature range of $200{\sim}470^{\circ}C$. The properties and performance of catalysts were characterized by the X-ray diffraction (XRD) and Brunauer Emmett Teller (BET). The catalytic activities of manganese oxide catalysts for acetaldehyde combustion were in the order of MnO < $MnO_2$ < $Mn_2O_3$ < $Mn_3O_4$, and it is similar to that of propionaldehyde combustion. We also confirmed that the reactions have well followed the kinetic model of Power-Rate Law and the reaction order (n) is 1 for both of the acetaldehyde and propionaldehyde combustion. In addition, the reaction activation energy of acetaldehyde and propionaldehyde combustion over $Mn_3O_4$ were found to be $72.42\;kJmol^{-1}$ for 487~503 K and $51.14\;kJmol^{-1}$ for 473~533 K, respectively.
