Heterogeneous Catalytic Hydrogenation

Tutors: Dr Felix Roessler

Heterogeneous catalytic hydrogenation is of significant importance for the production of pharmaceuticals, nutraceuticals, flavours and fragrances, agrochemicals and fine chemicals. Indeed, an average of approximately 10% of all chemical steps in the production of such chemicals are catalytic hydrogenations. However, due to the multidisciplinary nature of heterogeneous catalytic hydrogenation, this technology is frequently improperly or inadequately used, which results in problems during scale up and negatively affects the economy of chemical processes and the quality of products.
Participants on this comprehensive course will be familiarized with all the important aspects of heterogeneous catalytic hydrogenation.

Attendees will learn how to successfully design, develop and realize economic, safe, foolproof and ecological hydrogenation processes. The main focus will particularly be on a deeper understanding of the underlying disciplines such as catalysis on surfaces and transport processes.

Guidelines on how to approach specific hydrogenation problems and concepts and tools for the design, development and scale up of catalytic hydrogenation processes will be presented, rather than summing up transformations of functional groups by catalytic hydrogenation, as this information can nowadays easily be searched and found in literature and patents.

Course Outline

The course covers the following topics:

  • Surfaces and metal surfaces
  • Theory of catalysis on surfaces
  • Transport steps and chemical steps in heterogeneous catalysis

  • Hydrogenation catalysts (catalyst types, catalyst preparation, catalyst properties, catalyst activation and deactivation)
  • Influence of solvents
  • Influence of acids, bases, additives, modifiers
  • Influence of substrates
  • Influence of reaction conditions (concentrations, temperature, agitation)
  • Chemical group transformations
  • Reaction engineering aspects: suspension and fixed bed reactors; batch, semibatch and continuous operation modes
  • Tools and guidelines for selection of chemical systems, determination of basic reaction data and successful scale up from laboratory to plant
  • Hydrogenation in laboratory and plant
