摘要： Devices, methods, and systems for carbon dioxide (CO2) sequestration using a cellulose nanofiber (CNF) aerogel, having a monolithic structure. The monolithic structure includes an aerogel matrix, a plurality of crosslinked CNFs, and a plurality of cellulose nanocrystal acetone (a-CNC) suspension particles, where the plurality of crosslinked CNFs and the plurality of a-CNC suspension particles are dispersed throughout the aerogel matrix. Systems and methods for CO2 sequestration include locating a CO2 producing process, separating, using a first membrane system, a feed stream into a mixed solid and liquid stream and a first gas stream and separating, using a second membrane system, the first gas stream to produce a second gas stream and a CO2 rich stream. Systems and methods further include directing the CO2 rich stream to a cellulose nanofiber (CNF) aerogel unit and adsorbing CO2 from the CO2 rich stream.
