A system and method for passive collection of atmospheric carbon dioxide is disclosed. The system includes a harvest chamber having a first opening and a sorbent regeneration system. The system also includes a capture body coupled to and movable by a support structure. The capture body includes a sorbent material and is movable by the support structure to be in a collection configuration wherein at least a portion of the capture body is in contact with a natural airflow outside the harvest chamber such that atmospheric carbon dioxide is captured by the sorbent material, and a release configuration wherein at least a portion of the capture body holding captured carbon dioxide is operated upon by the regeneration system inside the harvest chamber such that captured carbon dioxide is released to form an enriched gas.

System and method for passive collection of atmospheric carbon dioxide

The present application focuses on systems and methods that utilize one or more carbon dioxide (CO) sorbent substrates and a swing cycle, e.g., a moisture swing cycle, to increase the partial pressure of the COin a gaseous feedstock, which is delivered through a membrane to a bioreactor, such as a membrane carbonation photobioreactor. Such systems and processes offer an effective means for concentrating and capturing COobtained from air and delivering the concentrated COto a photobioreactor through a membrane.

Embodiments of the invention a method for producing a composite paper by providing a particulate sorbent, providing a paper pulp, and mixing the particulate sorbent and the paper pulp to develop a mixture. The method includes producing an article from the mixture that includes the particulate sorbent at least partially distributed through at least a portion of the article. Further, the at least one article is configured and arranged to uptake and release carbon dioxide as a function of moisture content. Some embodiments of the invention include a composite paper-like assembly including at least a first and second layer including hydrophobic fibers, and sorbent particles and/or a sorbent loaded paper sandwiched between the first and second porous sheets. Some further embodiments include a method for producing a material that supports a moisture swing by providing a material including activated carbon, and infusing the activated carbon with ionic salt.

A carbon dioxide capture and release method of forming a MOF matrix material including at least one metal-organic-framework crystal that includes at least one metal ion or metal ion cluster coordinated to polydentate organic ligands. The method includes forming a positive moisture swing COhost by application of at least a portion of the MOF matrix material to at least a portion of a good, and exposing the good to a feed gas. The method also includes altering the absorption and desorption of COin the COhost through a swing absorption/desorption process of moisture content, where an equilibrium pressure of COover the COhost is based at least in part on the moisture content. The metal-organic-framework crystal can be UIO-66 including ZrO(OH)(CO)clusters linked by terephthalate acid ligands, and/or ZrO(OH)(CO)clusters linked by amino-terephthalic acid ligands, and/or ZrO(OH)(CO)clusters linked by nitro-terephthalic acid ligands.
