Yu, Qian; Brilman, Wim (2020): A Radial Flow Contactor for Ambient Air CO2 Capture

Yu, Qian; Brilman, Wim (2020): A Radial Flow Contactor for Ambient Air CO2 Capture. In Applied Sciences 10 (3), p. 1080. DOI: 10.3390/app10031080.

"In this paper, the performance of a new radial flow reactor (RFR) for CO2 adsorption from ambient air is reported. The reactor uses a supported amine sorbent and is operated in a batch mode of operation or semi-continuously, respectively without or with sorbent circulation."

Gambhir, Ajay, and Massimo Tavoni (2019): Direct Air Carbon Capture and Sequestration: How It Works and How It Could Contribute to Climate-Change Mitigation

Gambhir, Ajay, and Massimo Tavoni (2019): Direct Air Carbon Capture and Sequestration: How It Works and How It Could Contribute to Climate-Change Mitigation. One Earth 1 (4): 405–9. https://doi.org/10.1016/j.oneear.2019.11.006.

‌"Here, we explain how DACCS works, focusing on two major processes that have been developed into large-scale pilot plants. We discuss cost estimates and operational energy requirements, as well as ecological and ethical considerations. We highlight the role of DACCS in the low-carbon transition by discussing its benefits, while also noting potential trade-offs and uncertainties that deserve further investigation."
