Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.


After the course the student

  1. knows the principles of heterogeneous catalysis
  2. recognizes the steps (diffusion, adsorption/desorption, surface reaction) in heterogeneously catalyzed reactions
  3. knows the types of homogeneous catalysis and is able to derive rate equations of acid/base catalyzed homogeneous reactions
  4. can derive rate equations based on steps of heterogeneously catalyzed reactions
  5. knows the different forms of deactivation of heterogeneous catalysts and can derive rate of deactivation based on the type  of deactivation
  6. is able to evaluate existence of diffusion limitations in heterogeneously catalyzed reactions
  7. can use methods applied for the evaluation of internal and external diffusion limitations in heterogeneous catalysis
  8. can combine the rate equations of heterogeneously catalyzed reactions to reactor mass balance equations and use these equations for the reactor design
  9. knows the principles of the mechanical strength of solid catalysts in the packed catalyst beds
