What’s ACTIVATED CARBON?
Activated carbon (also known 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 a higher level surface reactivity, activated carbon enable you to purify, dechlorinate, deodorize and decolorize both liquid and vapor applications. Moreover, activated carbons are economical adsorbents for many industries including water purification, food grade products, cosmetology, automotive applications, industrial gas purification, petroleum and rare metal recovery mainly for gold. The bottom materials for activated carbons are coconut shell, coal or wood.
Use of ACTIVATED CARBON
Several types of activated carbon are suited 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 the correct activated carbon product and mesh size is determined by the approval and contaminants you plan to remove.
Typical applications are:
Eliminating chemical toxins including Benzene, TCE, and PCE.
Hydrogen Sulfide (HS) and removal of waste gases
Impregnated activated carbon used as a bacteria inhibitor in h2o filters
Removal of taste and odor causing compounds including MIB and geosmin
Recovery of gold
Removal of chlorine and chloramine
Designing a proper activated carbon filtration with enough contact time, pressure drop, and vessel dimension is important. Also, activated carbon’s physical and chemical characteristics play a huge role in removing contaminants effectively. Therefore, material testing is essential and ASTM test methods such as butane activity, floor, density, and water content (moisture) can be done to find the best suitable material on your application.
Varieties of ACTIVATED CARBON
Coconut shell-based activated carbon
The very large internal surface areas characterized by microporosity in addition to high hardness and occasional dust make these coconut shell carbons particularly attractive for water and important air applications as well as point-of-use water filters and respirators
High floor characterized by a large proportion of micropores
High hardness with low dust generation
Excellent purity, with most products exhibiting no more than 3-5% ash content.
Renewable and green raw material.
Coal-based activated carbon
It makes different performance characteristics in industrial applications typically focused on with coal or coconut products.
Wood based activated carbon carries a high area characterized by both mesopores and micropores and it has excellent decolorizing properties due to its signature porosimetry
Catalytic based activated carbon
Catalytic carbon is often a sounding activated carbon used to remove chloramines and hydrogen sulfide from h2o.
They have all the adsorptive characteristics of conventional activated carbons, and also the ability to promote chemical reactions.
Catalytic carbon is not impregnated with caustic chemicals
Because catalytic carbons have zero impregnates, you won’t have to worry about reduced organic odor capacity or perhaps the higher bed fire potential with the impregnated carbons.
Catalytic carbon is created by altering the top structure of activated carbon. It really is modified by gas processing at high temperatures to alter the electronic structure and build the very best a higher level catalytic activity on carbon for reducing chloramine and H2S in water. This added catalytic functionality is significantly in excess of that seen in traditional activated carbons. Catalytic carbon is surely an economical means to fix treat H2S levels as high as Twenty to thirty ppm. Catalytic carbon converts adsorbed H2S into sulfuric acid and sulfurous acid which can be water soluble, so carbon systems can be regenerated with water washing to bring back H2S convenience of less frequent physical change-outs.
Relatively low density
Renewable supply of raw material
Impregnated Activated Carbon
Surface impregnation chemically modifies activated carbon by way of a fine distribution of chemicals and metal particles about the internal surfaces of the company’s pores. This greatly increases the carbon’s adsorptive capacity through a synergism between your chemicals along with the carbon. And supplies a cost-effective method to remove impurities from gas streams which would otherwise not possible.
Water treatment
Due to its antimicrobial/antiseptic properties, silver-impregnated carbon is an efficient adsorbent for purification in earth-bound domestic and other water systems.
Gas purification
Impregnated activated carbon is used to help remedy flue gases in coal-fired generation plants and other air pollution control applications. Carbon could be specifically impregnated for removing acid gases, ammonia and amines, aldehydes, radio-active iodine, mercury and inorganic gases like arsine and phosphine. Carbon impregnated with metal-oxide targets inorganic gases including HCN, H2S, phosphine and arsine.
