Direct Air Capture (DAC) of CO2 accomplished by different alkanolamines
, 2018 The chemical capture of carbon dioxide from ambient air (Direct Air Capture - DAC) represents one of the negative carbon technologies (NETs) with the potential of reduce the global atmospheric CO2 concentration. Moreover, the capture of CO2 from air is suitable to supply pure CO2 wherever it is needed.

Process modelling of Direct Air Capture (DAC) of CO2 using solid amine sorbents
, 2022 This paper presents a fixed bed reactor system to capture CO2 from ambient air via Temperature Vacuum Swing Adsorption (TVSA) cycles employing Lewatit® VP OC 1065 amine-functionalized adsorbents. Firstly, a model describing CO2 mixture flow, mass, and heat transfer with adsorption isotherm model is developed in Aspen Adsorption environment to study the

Scaling Direct Air Capture (DAC): A moonshot or the sky's the limit?
2023Direct Air Capture technology coupled with geological storage ('DACS', also 'DACCS') has recently emerged as one of the main carbon dioxide removal (CDR) needed to reach net-zero targets. If deployed at scale, DACS would result in 'negative emissions' which would preclude the need for riskier options to abate emissions, such as geo-engineering ...

The utility of MOF-based materials in direct air capture (DAC) application to ppm-level CO2
Environmental ResearchMetal-organic frameworks (MOFs) are well-suited materials for CO2 removal and have robust capture capacity and selectivity. Although the adsorption of CO2 in MOFs has been studied, the implementation of ppm-level CO2 uptake in MOFs and the effects of the pore size and charge have not been fully explored.
