Key facts

Literature research on the state of the art of CO2-active FT: achievable conversions and selectivities, iron catalysts used, reported lifetimes and deactivation mechanisms
Construction of a steady-state process model of the CO2-active FT route (electrolysis, CO2 supply, intensified FT reactor) in Aspen Plus, with a suitable reactor model
Definition of a reference case (separate RWGS reactor with downstream conventional FT) as a benchmark to quantify the effect of process intensification
Techno-economic and, where appropriate, ecological evaluation of the simulation results with Python
Break-even analysis: At which combination of catalyst activity, C5+ selectivity and lifetime does the CO2-active route become competitive compared to the reference case?

Studies in process engineering, chemical engineering or a comparable degree programme
Very good programming skills (e.g. Python, MATLAB, C++)
Good knowledge of flowsheet simulation software (e.g. Aspen Plus®, CHEMCAD)
Very high learning ability, initiative and independence

DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees in their personal and professional environment. For this purpose, our numerous training and further education opportunities are available to you. Equal opportunities are a particular concern for us; we therefore want to increase the proportion of women in science and management. Applications from severely disabled persons are given preference in case of professional suitability.
