Abstract

The invention discloses a composite carbon dioxide adsorption material, which includes an in-situ synthesized MOFs(metal-organic frameworks)-graphite based composite material and organic amine loaded on the MOFs-graphite based composite material. The mass ratio of the MOFs-graphite based composite material to the organic amine is 0.1-10:1. The composite carbon dioxide adsorption material provided by the invention realizes the combined action of physical adsorption and chemical adsorption, can adsorb and store carbon dioxide at medium and low temperature, and realizes regeneration and reuse of the adsorbent under certain conditions. The composite carbon dioxide adsorption material has good adsorption capacity, high selectivity and cycling stability on carbon dioxide, and can overcome the disadvantages of easy volatilization and easy corrosion of equipment in organic amine so as to meet the industrial processing requirements. The invention also discloses a preparation method of the composite carbon dioxide adsorption material and application in adsorption of carbon dioxide in flue gas.

Description

technical field

[0001] The invention relates to the field of preparation of carbon dioxide adsorbents, in particular to a composite carbon dioxide adsorbent material and its preparation method and application. Background technique

[0002] In recent years, the increasing use of fossil fuels has resulted in CO 2 Emissions continue to increase. Over the past 250 years, atmospheric CO 2 The concentration increased from 280ppm before the industrial revolution to 390ppm in 2010, especially in the past 50 years. Its excessive emissions have caused global warming, seriously affecting the earth's ecological environment and climate change. Therefore, CO 2 Emission reduction has also become an urgent issue. The development of low-carbon new energy and the improvement of existing energy efficiency are both CO 2 effective way to reduce emissions, while CO 2 Capture and separation technology is undoubtedly an effective way to reduce CO 2 emission technology.
