Abstract

The invention provides a CO2 adsorbent and a preparation method thereof, the CO2 adsorbent comprises a porous carrier and organic amine, and the organic amine is loaded on the surface and in pore channels of the porous carrier in a few-layer manner. According to the CO2 adsorbent provided by the embodiment of the invention, the adsorption performance of the organic amine can be fully exerted, so that the CO2 adsorbent can effectively adsorb low-concentration CO2 in a normal-temperature environment.

Description

technical field [0001] The present application relates to the technical fields of gas separation, gas purification and material chemistry, in particular to a CO 2 Adsorbent and method of making the same. Background technique [0002] At present, passive houses are generally used in building energy conservation to reduce energy consumption, but the energy-saving measures for fresh air energy consumption are not ideal. [0003] In response to the above problems, although CO 2 Sorbent for indoor CO 2 The adsorption and desorption cycle purification technology of other gas pollutants reduces the outdoor air intake and improves the utilization rate of indoor regeneration air, thereby achieving the purpose of reducing the energy consumption of fresh air. [0004] However, existing CO 2 The preparation process of the adsorbent requires first dissolving the organic amine in an organic solvent, dipping the carrier in the amine solution, and then drying it for a long time. The pre...
