Maika Klemmer

During her studies, Maika Klemmer investigated the possibility to continuously produce bio-oil out of biomass. The process involves watery biomass slurries at high pressures and temperatures which form an oily product that resembles crude oil and could be used as a substitute for the latter. Maika Klemmer studied the processability of different biomass types and compared the reactor to different reactor types.

The new research findings contribute to the understanding of continuous bio-oil production and its scale-up for future industrial usage.

The PhD degree was completed at the Institute for Inorganic Chemistry, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
