Abstract

The presence of water (H2O) is essential for the adsorption of carbon dioxide (CO2) on the serpentine particles. However, the use of H2O in the slurry bed columns requires high energy inputs to maintain the temperature during operation above ambient temperatures. Moreover, the separation, drying, handling, and processing of the product stream will pose challenges and cost even more energy. Here, we show the proof of principle of CO2 sequestration on mineral particles in a fluidized bed using a moist CO2 stream. The setup allows wetting of the particles while maintaining fluidization. The results show 50% mineral conversion and 40% CO2 conversion in 8 min at 1 bar and 90 °C.
