Important Info On Activated Carbon

WHAT IS ACTIVATED CARBON?

Activated carbon (also referred to as activated charcoal, activated coal or active carbon) is an extremely useful adsorbent. Due to their high floor, pore structure (micro, meso and macro), and high degree of surface reactivity, activated carbon may be used to purify, dechlorinate, deodorize and decolorize both liquid and vapor applications. Moreover, activated carbons are economical adsorbents for several industries like water purification, food grade products, cosmetology, automotive applications, industrial gas purification, petroleum and yellow metal recovery mainly for gold. The camp materials for activated carbons are coconut shell, coal or wood.

Using ACTIVATED CARBON

Various kinds of activated carbon are fitted to various specialized applications.

Granulated activated carbon
Pelletized activated carbon
Powdered activated carbon
Impregnated activated carbon

Catalytic activated carbon

Each grade and height and width of activated carbon is application specific. Choosing correct activated carbon product and mesh size is determined by the application form and contaminants you intend to remove.

Typical applications are:

Removal of chemical toxins for example Benzene, TCE, and PCE.
Hydrogen Sulfide (HS) and eliminating waste gases
Impregnated activated carbon used as a bacteria inhibitor in mineral water filters
Elimination of taste and odor causing compounds like MIB and geosmin
Recovery of gold
Eliminating chlorine and chloramine
Designing an appropriate activated carbon filtering system with enough contact time, pressure drop, and vessel dimensions are important. Also, activated carbon’s physical and chemical characteristics play a vital role in removing contaminants effectively. Therefore, material exams are essential and ASTM test methods like butane activity, surface, density, and water content (moisture) can be accomplished for top level suitable material to your application.

Kinds of ACTIVATED CARBON

Coconut shell-based activated carbon

Abdominal muscles large internal surface areas characterized by microporosity as well as high hardness and occasional dust make these coconut shell carbons particularly attractive for water and demanding air applications in addition to point-of-use water filters and respirators

Very high surface area seen as an a large proportion of micropores
High hardness with low dust generation
Excellent purity, with most products exhibiting only 3-5% ash content.
Renewable and green raw material.

Coal-based activated carbon

It produces different performance characteristics in industrial applications typically catered to with coal or coconut products.

Wood based activated carbon includes a high floor characterized by both mesopores and micropores and has excellent decolorizing properties because of its signature porosimetry

Catalytic based activated carbon

Catalytic carbon can be a type of activated carbon used to remove chloramines and hydrogen sulfide from normal water.

It has all the adsorptive characteristics of conventional activated carbons, and also the power to promote chemical reactions.

Catalytic carbon is not impregnated with caustic chemicals
Because catalytic carbons have no impregnates, you won’t need to panic about reduced organic odor capacity or even the higher bed fire potential of the impregnated carbons.

Catalytic carbon is created by altering the surface structure of activated carbon. It can be modified by gas processing at high temperatures to switch the electronic structure and make the best amount of catalytic activity on carbon for reducing chloramine and H2S in water. This added catalytic functionality is really a lot higher than that present in traditional activated carbons. Catalytic carbon is surely an economical means to fix treat H2S levels as high as Twenty or thirty ppm. Catalytic carbon converts adsorbed H2S into sulfuric acid and sulfurous acid that happen to be water soluble, so carbon systems can be regenerated with water washing to bring back H2S ability to more uncommon physical change-outs.

Relatively low density
Renewable source of raw material

Impregnated Activated Carbon

Surface impregnation chemically modifies activated carbon via a fine distribution of chemicals and metal particles on the internal surfaces of the company’s pores. This greatly increases the carbon’s adsorptive capacity through a synergism between the chemicals as well as the carbon. And supplies a cost-effective strategy to remove impurities from gas streams which could otherwise not possible.

Water treatment
For the 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 utilized to treat flue gases in coal-fired generation plants and also other air pollution control applications. Carbon could be specifically impregnated for elimination of acid gases, ammonia and amines, aldehydes, radio-active iodine, mercury and inorganic gases for example arsine and phosphine. Carbon impregnated with metal-oxide targets inorganic gases including HCN, H2S, phosphine and arsine.
