ABSTRACT

Reducing CO2 emission is the main challenge of our generation. The transition towards low carbon energy sources will take time and CO2 capture, either at emission sources or directly from the atmosphere, is a mitigation solution currently in fast development. CO2 capture is a cyclic process, with a first adsorption step who removes CO2 from a gas stream, followed by a thermal regeneration step, which yields highly concentrated CO2, which can be reused or stored. However, when directly captured from the atmosphere (~ 400 ppm), this process has a high cost ((100-400€/tCO2),[1],[2] due mainly to the energy needed during the regeneration step (~1500 kWh/tCO2). The PhD thesis candidate will synthesize new polyamines and study their interactions with CO2 and water with the objective of reducing the energetic cost of CO2 capture and to improe their thermal stability.
