Problems solved by technology

[0003] In addition, when the concentration of carbon dioxide in the air exceeds 2%, it will cause damage to the organs of the human body. When the concentration of carbon dioxide exceeds the standard concentration, the body will be poisoned, and the high concentration of carbon dioxide will cause suffocation.

Abstract

The invention relates to the field of air purification, and particularly discloses a method for adsorbing carbon dioxide in air. The method comprises the following steps: S1, preparing a carbon molecular sieve; s2, adsorbing CO2 gas; s3, CO2 gas is released. The preparation method has the advantage that the carbon emission content in air is reduced.

Description

technical field [0001] This application relates to the field of air purification, more specifically, it relates to a method for adsorbing carbon dioxide in the air. Background technique [0002] Since the industrial revolution, the carbon dioxide and other heat-absorbing greenhouse gases that humans have emitted into the atmosphere have increased year by year, and the greenhouse effect of the atmosphere has also increased, which has caused a series of serious problems such as global warming. The natural environment creates a natural greenhouse effect. The greenhouse effect will increase the temperature, leading to global warming, and then the glaciers will retreat, the permafrost will melt, and then the sea level will rise, rivers and lakes will freeze or thaw early, seasons will change, and climate will produce abnormalities. will become extinct, bacterial plague will spread for a long time, global food production will be reduced, and many people will face famine. [0003...
