Capturing Atmospheric CO2 for Microalgae Cultivation

W. Brilman, L. Garcia-Alba, M. Vos & R. Veneman
In this work, we propose and demonstrate the concept of atmospheric CO2 capture for algae cultivation (and horticulture) as alternative to flue gas derived CO2. A supported amine sorbent was prepared and found able to capture CO2 at atmospheric conditions (around 400 ppm, 2-2.5 mole CO2/kg sorbent) and releasing it at higher pressures and purity. Adsorption capacities were determined for CO2 concentrations from 200 ppm to 10 vol% and temperatures up to 55°C. Regeneration was...
