APPLICATION OF ACTIVATED CARBON

Impregnated Activated Carbon

Surface impregnation chemically modifies activated carbon through a fine distribution of chemicals and metal particles on the internal surfaces of its pores. This greatly enhances the carbon’s adsorptive capacity through a synergism between the chemicals and the carbon. And provides a cost-effective way to remove impurities from gas streams which would otherwise not be possible.

 

Water treatment

Because of its antimicrobial/antiseptic properties, silver-impregnated carbon is an effective adsorbent for purification in earth-bound domestic and other water systems.

 

Gas purification

Impregnated activated carbon is used to treat flue gases in coal-fired generation plants and other air pollution control applications. Carbon can be specifically impregnated for removal of acid gases, ammonia and amines, aldehydes, radio-active iodine, mercury and inorganic gases such as arsine and phosphine. Carbon impregnated with metal-oxide targets inorganic gases including HCN, H2S, phosphine and arsine.

 

APPLICATION OF ACTIVATED CARBON

Different types of activated carbon are suited for various specialized applications.

Each grade and size of activated carbon is application specific. Selecting the correct activated carbon product and mesh size depends on the application and contaminants you plan to remove.

Typical applications are:

  • Removal of volatile organic compounds such as Benzene, TCE, and PCE.
  • Hydrogen Sulfide (HS) and removal of waste gases
  • Impregnated activated carbon used as a bacteria inhibitor in drinking water filters
  • Removal of taste and odor causing compounds such as MIB and geosmin
  • Recovery of gold
  • Removal of chlorine and chloramine

Designing a proper activated carbon filtration system with enough contact time, pressure drop, and vessel size is important. Also, activated carbon’s physical and chemical characteristics play an important role in removing contaminants effectively. Therefore, material testing is essential and ASTM test methods such as butane activity, surface area, density, and water content (moisture) can be carried out to find the best suitable material for your application.

What is Activated Carbon

图片
Activated carbon is one of the most common adsorption media   used on filters to control indoor air quality and reduce pollutants. The popularity of activated carbon is due to its inherent ability to adsorb most organic chemicals due to the large surface area created by the increased activation on the carbon/charcoal surface. When it comes to the capture and control of gaseous compounds present in the indoor air space, activated carbon will quickly and effectively trap these contaminants on this activated filter media. In some cases, the charcoal/carbon material will be treated with additional chemicals during the activation of this material, which will be done through the use of a chemical called potassium permanganate. Potassium permanganate is used in activated carbon filter media to help attract reactions between the carbon media and the oxidation of polar or low molecular weight compounds. In addition, many manufacturers use this chemical additive on carbon filters to help extend

Waste Carbon Recovery for Environmental Sustainability

图片
Used granular (GAC) or extruded (EAC) activated carbon can be recycled through thermal activation, which involves treating the used carbon in a high temperature activation oven at 850°C or above. Recovery by thermal regeneration is only one of the steps in the complete service package. The recovery process consists of two main processes: 1) reactivation process and 2) tail gas treatment and energy recovery process.     The reactivation process itself can be subdivided into four steps. 1) Drying of used carbon The used carbon is fed into the furnace and heated from ambient temperature to 105 - 110°C. Water and some low boiling compounds are evaporated and released into the furnace atmosphere. As long as there is water in the pores,  the temperature of the carbon  remains between 105 and 110°C. 2) Desorption of low boiling point organics. As the carbon dries, the temperature increases further to about 450°C. During this temperature increase, various organic compounds are desorbed from th
