▎ 摘　　要

NOVELTY - Carbon dioxide organic amine adsorbent comprises at least one nano-material carriers and organic amines supported on the carrier materials. The carbon dioxide molecules have been pre-anchored on the organic amine. USE - Used as carbon dioxide organic amine adsorbent. ADVANTAGE - The method: adopts a pre-anchor strategy to improve the amine efficiency of organic amines, combines the easily agglomerated organic amine molecules with carbon dioxide molecules in advance and combines them with the carrier to ensure that each amine atom has the possibility of binding with carbon dioxide. The carbon dioxide adsorbent: has extremely high amine efficiency and excellent cycle stability, can adsorb carbon dioxide molecules efficiently and quickly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing carbon dioxide organic amine adsorbent, comprising (i) taking a silane coupling agent with an amine group or a long alkyl chain as an organic amine source, mixing with surfactant and ethanol, fully stirring to dissolve to prepare a precursor liquid and (ii) introducing the precursor liquid and carrier material into a stirred reactor, passing carbon dioxide gas, fully reacting, carrying out suction filtration, washing and drying to obtain carbon dioxide organic amine adsorbent prepared by pre-anchoring method.
