Methane Synthesis on Mars
The Bachelor thesis (Ba-MoSi 2021 in German) analyzed a chemical reactor for synthesis of methane on Mars using the Aspen Plus simulation software. The conditions at Mars are really exciting for chemical reaction engineers.
The Master thesis (Ma-MoSiExp 2021) investigated the oxidation of methane into syngas at temperatures up to 1000°C for application in chemical looping. Syngas can be used in a next step for e-fuels synthesis.
Continuous Particle Synthesis
Based on a Bachlor thesis (Ba-Exp 2016 in German) we published a scientific paper in May 2017 on the continuous synthesis of nanostructured Co3O4@SiO2 core-shell particles using a laminar-flow reactor.
Highly Dynamic Experiments
Very fast periodic experiments allow to analyze the elementary steps in heterogeneous catalysis resolved for each individuel reactand, which was done in a Master thesis (Ma-Exp 2021).
Dynamic Reactor Behavior
In August 2017 we successfully published a scientific paper analyzing the dynamic behavior of continuously stirred tank reactors based on a Bachelor thesis (Ba-MoSi 2016 in German).
Limited by Chemical Equilibrium?
If yes: The Master thesis (Ma-Exp 2021) investigated sorption-enhanced methanation, in order to shift the chemical equilibrium towards the product side. The challenge is the dynamic operation of the reactor, which is then needed.
