초록정보

Metal impregnated MCM-41 catalysts were prepared and their activities and selectivities were investigated for the oxidation reaction of trichloroethylene. Reactions were carried out with 1500ppm of TCE and 14000ppm of water in the feed stream at 300℃~500℃ at atmospheric pressure. In the TCE oxidation, $Cr_2O_3$/MCM-41 catalyst was deactivated. The deactivation of $Cr_2O_3$/MCM-41 seemed to be due to the loss of $Cr_2O_3$ complex formed with chlorine. The chromium loading of 6wt% $Cr_2O_3$ on MCM-41 showed a better activity than 3, 12wt% loading. This activity with different loading was in the same line with the amount of acidity as measured with $NH_3$ TPD. The emission of CO decreased with metal loading. The addition of water in the feed was necessary to reduce the formation of chlorine due to the stoichiometry. In the case of 6wt% $Cr_2O_3$/MCM-41, water lowered the catalytic activity and reduced the CO emission. The incorporation of Pd or Co in 6wt% $Cr_2O_3$/MCM-41 resulted in the decrease of catalytic activity. However, Pd lowered the CO emission and Co enhanced the resistance to the deactivation of catalyst.
