Wilson, Sean M. Wynn, and F. Handan Tezel (2020): Direct Dry Air Capture of CO2 Using VTSA with Faujasite Zeolites

Wilson, Sean M. Wynn, and F. Handan Tezel (2020): Direct Dry Air Capture of CO2 Using VTSA with Faujasite Zeolites. Industrial & Engineering Chemistry Research. https://pubs.acs.org/doi/abs/10.1021/acs.iecr.9b04803.

‌"In the process studied, a basic four step TVSA cycle comprising the following steps: pressurization with feed, adsorption, blowdown, and desorption was investigated first. Four different regeneration temperatures were tested along with four different gas space velocities."

Sen, Raktim, et al. (2020): Hydroxide Based Integrated CO2 Capture from Air and Conversion to Methanol

Sen, Raktim, Alain Goeppert, Sayan Kar, and G.K. Surya Prakash (2020): Hydroxide Based Integrated CO2 Capture from Air and Conversion to Methanol. Journal of the American Chemical Society. https://pubs.acs.org/doi/abs/10.1021/jacs.9b12711.

‌"We postulate that the high capture efficiency and stability of hydroxide bases make them superior to existing amine-based routes for direct air capture and conversion to methanol in a scalable process."

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."

Power, Ian M.; et al. (2020): Prospects for CO2 Mineralization and Enhanced Weathering of Ultramafic Mine Tailings from the Baptiste Nickel Deposit in British Columbia, Canada

Power, Ian M., Gregory M. Dipple, Peter M.D. Bradshaw, and Anna L. Harrison (2020): Prospects for CO2 Mineralization and Enhanced Weathering of Ultramafic Mine Tailings from the Baptiste Nickel Deposit in British Columbia, Canada. International Journal of Greenhouse Gas Control 94 (March): 102895. https://doi.org/10.1016/j.ijggc.2019.102895.

‌"Experiments were conducted using metallurgical test samples and pulps from cores with the aim of determining the potential for this deposit to sequester CO2 via direct air capture of atmospheric CO2 and carbonation using CO2-rich gas. The experimental direct capture rate was 3.5 kg CO2/m2/yr and would sequester 17 kt CO2/yr based on year-round reaction and when extrapolated to the scale of the proposed tailings facility (5 km2)."
