Direct flue gas mineral carbonation is an efficient way to reduce industrial greenhouse gas emissions. Along with other silicates, serpentine minerals show great potential for carbonation. Most of all, serpentine minerals are of significant interest due to their large availability and accessibility. With more than 2Gt of serpentine mining residues close to industrial emitters, the abatement potential is very important in the Province of Quebec. Nevertheless, serpentine needs to be heat activated to allow for sufficient carbonation rates. This processing step is responsible for high energy demand and needs to be optimized to allow for viable industry adoption. This study outlines a mineralogical approach using the Rietveld refinement method for quantitative XRD combined with flow-through time-resolved analysis (FT-TRA) and carbonation experiments to understand the impacts of thermal treatment on the dissolution of serpentine and the carbonation process.
