Preparation method of CO2 solid adsorbent with organic amine immobilized by chemical bonds

The invention belongs to the technical field of gas adsorption separation, and discloses a preparation method of a CO2 solid adsorbent with organic amine immobilized by chemical bonds. The preparationmethod comprises the following steps: (1) activating carboxyl; (2) carrier surface modification; (3) chemical bond reaction immobilization; and (4) preparing the solid adsorbent. The CO2 solid adsorbent prepared by the preparation method is efficient and stable, the larger pore diameter and active hydroxyl of the carrier MPS are beneficial to improving the CO2 capture amount, carboxyl groups areintroduced through surface modification to form chemical bond immobilization, the stability of the solid amine adsorbent is improved, uniform distribution of organic amine in pore passages is supported, the immobilization capacity of the organic amine on the carrier and the cyclicity and stability of the adsorbent are improved. 本发明属于气体吸附分离技术领域，公开了一种由化学键固载有机胺的CO2固体吸附剂的制备方法，包括：(1)羧基的活化；(2)载体表面修饰；(3)化学键反应固载；(4)固体吸附剂制备。本发明提供的制
