As an efficient adsorption material, activated carbon is widely used in the field of gas treatment. Its application is mainly based on the huge surface area and rich pore structure of activated carbon, which makes it have extremely strong adsorption capacity. The following are several main applications of activated carbon in gas treatment:
1. Air purification
Activated carbon is used in air purifiers and industrial air purification equipment, which can effectively adsorb harmful gases and odors in the air, such as:
Formaldehyde
Benzene
Hydrogen sulfide
Sulfur dioxide
Volatile organic compounds (VOCs)
Application scenarios:
Home air purifiers
Air treatment devices in offices and public places
2. Industrial waste gas treatment
In the industrial production process, a variety of harmful gases and pollutants will be generated. Activated carbon can effectively remove these gases to protect the environment and human health.
Application areas:
Chemical industry: removal of organic solvents and toxic gases
Pharmaceutical industry: purification of waste gas generated in the pharmaceutical process
Petrochemical industry: adsorption of hydrocarbon compounds and other volatile organic compounds
Printing, coating and paint industry: removal of volatile organic compounds
3. Automobile exhaust treatment
Automobile activated carbon canister (carbon canister) is used to capture fuel vapor released from the automobile fuel system to prevent it from being directly discharged into the atmosphere.
Function:
Adsorb fuel vapor and reduce volatile organic compound emissions
Improve the quality of automobile exhaust emissions
4. Adsorb harmful gases and odors
In some special occasions, such as laboratories, medical institutions, food processing enterprises, etc., activated carbon is used to adsorb and remove harmful gases such as ammonia and hydrogen sulfide, as well as odors generated during food processing.
5. Flue gas desulfurization and denitrification
Activated carbon plays a key role in flue gas desulfurization and denitrification. It can adsorb and catalyze the reaction to remove sulfur dioxide (SO₂) and nitrogen oxides (NOx) in flue gas.
6. Gas separation and purification
Activated carbon is used to separate and purify certain gases, such as hydrogen (H₂), nitrogen (N₂) and oxygen (O₂), and is mainly used in the chemical, electronic and pharmaceutical industries.
Summary
Activated carbon has a wide range of applications in gas treatment and has significant effects. With its excellent adsorption properties, it has become an important material for environmental protection and industrial gas purification. It plays a vital role in homes, industries and various professional fields.
