Dr. Arend Rösel

Research Field

In my research, I am working on the decenrtalized production of ammonia as a local energy storage from renewable energies. The fokus is on Haber-Bosch catalysts of the second generation. The aim is to develop a flow reactor as well as the associated process on the laboratory scale and its transfer to the industrial scale.

Biocatalysis

In the ComBioCat project, my goal is to replace conventional synthetic pathways with more efficient enzymatic reactions. For that I am using lipases which will be immobilized by different routes, to enable their application in a microreaction system.
