About the Catalysis for Energy Group (CEG)

The Catalysis for Energy Group (until 2009: Exhaust Gas After-treatment group) started in the late '80s as one of the first research groups worldwide to explore the urea-SCR process for NOx reduction in mobile Diesel engines. Ever since we are conducting research and development projects on different aspects of this fascinating technology, ranging from basic research up to applications at real Diesel engines and stationary power plants:
  • Catalyic and non-catalytic urea decomposition
  • Alternative liquid NH3 precursor compounds
  • Development of NH3 generators for mobile applications
  • Hydrolysis catalysts for urea and alternative liquid NH3 precursor compounds
  • SCR catalyst research and development: V2O5/WO3-TiO2, iron- and copper-exchanged zeolites, rare earth metal oxides
  • SCR chemistry: Standard-SCR reaction, Fast-SCR reaction, NO2-SCR reaction
  • Side-reactions: NH3 oxidation, N2O formation, NH4NO3 deposition and decomposition
  • SO2 oxidation over V2O5/WO3-TiO2
  • HC oxidation over V2O5/WO3-TiO2
  • V-emissions from V2O5/WO3-TiO2
  • and many more...
Beside the urea SCR process we are also active on the following exhaust gas cleaning technologies:
  • Oxidation catalysts
  • Soot oxidation in particulate filters
  • SOx storage
  • Methane oxidation
In the last years we have cooperated with more than 40 companies worldwide in the field of exhaust gas catalysis: ABB, Abgaszentrum der Deutschen Automobilindustrie (ADA), Alantum, Alstom, Alzchem, AVL, BASF, SKW Piesteritz, Agrolinz Melamine International, Caterpillar, ClearEdge, Cristal Global, Daimler, Ecocat, Emitec, erphi electronic, Ceram, Grundfos, Hilite, IMI Vision, Interkat, IVECO, Kemira, Liebherr, MAN, Wacker, Fuchs Lubricants, Ciba Speciality Chemicals, Yara, MEL Chemicals, MTU, Rhodia, S&B Industrial Minerals, Süd-Chemie, Swenox, Tenneco, Umicore, Volkswagen, Zeochem. You are welcome to contact us and to discuss your problem with us!

We have a strong background in chemistry, analytics and catalysis, which we use to elucidate reaction networks and mechanisms and to develop new catalysts. With this competence we have broadened in recent years our activities from exhaust gas catalysis towards catalyst development for energy conversion processes in general to support the research activities of the Bioenergy and Catalysis Laboratory (LBK), of the Energy and Environment Research Division (ENE) and of other groups outside PSI.
