CH5026 Transport Phenomena in Catalysis


1.Familiarize with the basic principles of molecular and convective transport phenomena 2. Differentiate the roles played by convection, adsorption, diffusion and reaction in affecting the overall rate of reaction in heterogeneous catalysis 3. Discover the role of heat and mass transfer during chemical reactions occurring in homogeneous and heterogeneous catalysis 4. Develop awareness on the role of transport phenomena in catalytic processes relevant to the petrochemical industry
