Title:
CO2 REVERSIBLE ADSORPTION MATERIAL, COMPOSITION AND REGENERATION METHOD THEREOF, AND CO2 CAPTURE METHOD
Document Type and Number:
WIPO Patent Application WO/2024/087839
Kind Code:
A1
Abstract:
A use of a zinc-aluminum spinel particle as a CO2 reversible adsorption material, a CO2 reversible adsorption material and a CO2 reversible adsorption composition, a CO2 capture method, and a method for regenerating the CO2 reversible adsorption material or the CO2 reversible adsorption composition. The zinc-aluminum spinel particle having a specific microstructure has a "micropore" + "mesopore" porous structure and a relatively high specific surface area, thus having a function of adsorbing and capturing CO2 and being easy to regenerate. It may be used as a CO2 adsorption and capture material with great application potential. The CO2 capture method can realize direct air capture of CO2, can be adapted to a variety of application scenarios, and has good universal applicability.
