Impregnated activated carbon is a specially treated activated carbon with a layer of activator or chemical agent on its surface to enhance its ability to adsorb specific pollutants. Impregnated activated carbon is widely used in treating pollutants in water and air. The impregnating agent used can greatly improve the selective adsorption capacity of activated carbon for specific compounds.
Advantages and Disadvantages of Impregnated Activated Carbon
Advantages:
High adsorption performance: Impregnated activated carbon has been specially treated and has higher adsorption capacity, which is suitable for removing specific pollutants such as hydrogen sulfide and sulfur dioxide.
Strong resistance to high temperature and high pressure: Impregnated activated carbon can withstand high temperature and high pressure, is not easy to break, and has a long service life.
Wide application areas: Suitable for purification and refining of chemical raw material gas, gas for pharmaceutical industry, carbon dioxide gas for beverages, etc.
Disadvantages:
High cost: The production process of impregnated activated carbon is complicated and the cost is high, which is not suitable for large-scale low-cost applications.
Specific applications: Impregnated activated carbon is mainly used for specific gas purification tasks, and its application range is relatively narrow.
Therefore, if specific gaseous pollutants need to be removed, such as hydrogen sulfide, sulfur dioxide, etc., impregnated activated carbon is a better choice because of its high adsorption performance and resistance to high temperature and high pressure.
