Catalyst Design  

  Chemical feedstocks and energy storage – bridging the gap between fundamental research and industrial application  

  Fraunhofer is Europe’s largest application-oriented research organization. The Institute for Environmental, Safety, and Energy Technology UMSICHT in Oberhausen covers technical innovations in the fields of environmental, material, process and energy technology. The aim of the group »Catalyst Design« is the installation and establishment of a new competency in the field of heterogeneous catalysis within Fraunhofer as an attractive and reliable contact for the chemical industry. In close cooperation with the Laboratory of Industrial Chemistry, the group adopts and enhances catalytic concepts from the fundamental research, which are then transferred to realistic systems and processes of industrial relevance and finally led to innovative applications.
