Topic description

In the context of combating climate change, the capture and utilization of atmospheric CO₂ represent key levers for the decarbonization of industry. This thesis contributes to this effort by exploring an innovative strategy that combines CO₂ capture with its mineralization into calcium carbonate, a product with value in various industrial sectors.

The main objective is to develop a compact and intensified process based on the coupling of two advanced centrifugal technologies: the Rotating Packed Bed (RPB) for CO₂ capture via absorption, and the Spinning Disc Reactor (SDR) for the controlled precipitation of carbonate. This original configuration aims to overcome the limitations of conventional processes by enhancing mass transfer and chemical reaction control, while also reducing footprint and energy consumption.

The thesis will proceed in three stages:

Individual optimization of the RPB and SDR processes: studying optimal ...
