Efficient Adsorption-Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures. [PDF]

open access: yesAdv Sci (Weinh)
Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...

Data-driven simultaneous process optimization and adsorbent selection for vacuum pressure swing adsorption

open access: yesChemical Engineering Research and Design, 2022
Technologies for post-combustion carbon capture are essential for the reduction of greenhouse gas emissions to the atmosphere. However, they are still associated with high costs and energy consumption. Intensified processes for carbon capture have the potential to overcome these challenges due to their higher efficiency, lower capital cost, and ...
