Abstract

The invention relates to a carbon dioxide adsorption recovery method, and belongs to the field of environment protection. The carbon dioxide adsorption recovery method uses adamantyl porous polymers as a carbon dioxide absorption adsorption material, and comprises the following processes including an absorption adsorption process of contacting the adamantyl porous polymers and treatment objects soas to adsorb carbon dioxide, and a desorption process for of desorbing carbon dioxide from the adamantyl porous polymers adsorbingabsorbed with the carbon dioxide. The adamantyl porous polymers are used; the adsorption recovery of carbon dioxide gas is realized. The adamantyl porous polymers have good carbon dioxide adsorption performance.

Description

technical field [0001] The invention relates to a method for absorbing and recovering carbon dioxide, which belongs to the field of environmental protection. Background technique [0002] Carbon dioxide (carbon dioxide), chemical formula CO 2 . It is one of the main components in the air and a common greenhouse gas. A large amount of carbon dioxide gas is emitted into the atmosphere, which will cause climate change, bring about changes in the overall ecosystem, and affect food production and water supply. Therefore, all countries are promoting clean energy and reducing carbon emissions, and recycling captured carbon dioxide for reuse. [0003] Carbon dioxide has a very wide range of uses. Carbon dioxide is an important raw material for plant photosynthesis; carbon dioxide can be injected into beverages to increase the pressure, make the beverage contain bubbles, and increase the taste when drinking, such as soda and beer. Solid carbon dioxide (or dry ice) will vaporize a...
