Deactivation of Oxidation Catalysts

Abstract:

Activity and selectivity data for the oxidation of VOC containing air streams are reported over four commercial oxidation catalysts. The effect of VOC type and concentrations was investigated by using three different air streams containing VOCs typical of those expected from Air Force Groundwater air- strippers. The effect of reactor type was investigated by using the ARI catalyst both in the fixed bed and in the fluid bed reactor. The oxidation reaction was conducted for extended Periods of time at constant total conversion 99. The temperature was periodically increased to compensate for any loss in the intrinsic catalyst activity because of deactivation. The fresh and used catalysts were characterized to correlate the activity and selectivity with the physico-chemical properties of the catalyst.
