Abstract
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...
