Textured carbon capture composite (C3) films for distributed direct air capture in urban spaces

Carbon Dioxide Capture and Air Quality

Capture of carbon dioxide from ambient air

Carbon dioxide capture from ambient air could compensate for all carbon dioxide emissions to the atmosphere. Such capture would, for example, make it possible to use liquid, carbon-based fuels in cars or airplanes without negatively impacting the climate. We present a specific approach based on a solid sorbent in the form of an anionic exchange resin, that absorbs carbon dioxide when dry and re...

Assessment of reasonable opportunities for direct air capture

where i represents the input stream, r is the retentate, and p is the permeate. Minimum work is calculated from Eq. 2, and the real work is estimated from available pilot-scale data sourced from IECM. Specifically, the work attributed to any separation process can be interpreted as the incremental loss in net plant power output relative to a non-capture reference plant, levelized by the amount ...

Feasibility of Air Capture

Capturing CO2 from air, referred to as air capture, is being proposed as a viable climate change mitigation technology. Technically, air capture is not a new technology; industrial applications can be traced back to the 1930s. This paper explores the feasibility of this technology as a climate change mitigation option. Two different pathways of air capture are assessed: direct air capture, whic...

Carbon Dioxide Capture by Modified UVM-7 Adsorbent

In this study, bimodal meso-porous silica (UVM-7) synthesized and fabricated amino silane modified supports were characterized by powder X-ray diffraction (XRD), N2 adsorption/desorption, transmission electron microscope (TEM), elemental analysis and titration. Capacity of CO2 capture on modified bimodal pore structure silica at 70°C was calculated using breakthrough curves; and it was found th...
