A Mathematical Approach to the Balancing of Mass Transfer and Reaction Kinetics in Dual Kinetic Model for Automotive Catalysis

Evolution and Enabling Capabilities of Spatially Resolved Techniques for the Characterization of Heterogeneously Catalyzed Reactions

“…The major drawback of this approach is the limited predictive capabilities of such global-kinetics models . The intrinsic kinetics (also known as microkinetics) approach offers much more information about the processes occurring within the catalytic reactor but is significantly more complex and time-consuming to develop. , …”

“…The refinement of the mass transfer parameters resulted in a good correlation between the experimental and simulated conversion as a function of axial position profiles (Figure ). Interestingly, from the CO oxidation it was reported that the microkinetic approach was more effective than the global kinetic approach for predicting the profiles of the processes investigated . From the WGS study, both the global and microkinetic models were found to accurately describe the gas-concentration/conversion profiles …”
