Catalytic oxidation, as a proven control technology, has demonstrated a high level of efficiency in reducing Volatile Organic Compound (VOC`s) at competitive, and in many cases, lower cost than the other thermal incineration methods. Catalytic oxidation is the preferred technology for the destruction of VOC`s in a variety of industries; such as, flexographic printing, metal can coating, contract sterilization and bakeries. A key component of these catalytic systems is the catalyst itself, and transition metal oxide catalysts have demonstrated their advantage and overall superior applicability in numerous installations. The higher VOC destruction efficiencies of these catalysts, particularly for oxygenated VOC`s, allows for a lower temperature of operation making these catalysts an economically attractive alternative based upon the energy savings when compared to noble metal catalysts. Manganese based oxide catalysts are available in either homogenous extruded form or in monolith form, depending upon their application. The performance characteristics - measured as VOC destruction efficiencies - of these catalysts are dependent upon the operating conditions of the catalytic reactor. Reactor configuration and operating conditions; such as, catalyst operating temperature, gas phase linear velocity, contact time of the gas stream with the catalyst, and finally the characteristics of the hydrocarbon, all influence the efficiency of these catalytic systems. Models relating the hydrocarbon destruction efficiencies of these catalysts, as it is affected by these parameters, will be presented. These parametric models allow for comparison of various alternative catalyst strategies to be applied to a VOC destruction situation in the design phase. Data will be presented on a transition metal extruded catalyst, an extended temperature range manganese based catalyst, as well as a monolithic form of the transition metal catalyst.
