TYPES OF ACTIVATED CARBON
Activated carbon is a very useful adsorbent. Due to their high surface area, pore structure, and high degree of surface reactivity, activated carbon can be used to purify, dechlorinate, deodorize and decolorize both liquid and vapor applications. Moreover, activated carbons are economical adsorbents for many industries such as water purification, food grade products, cosmetology, automotive applications, industrial gas purification, petroleum and precious metal recovery mainly for gold. The base materials for activated carbons are coconut shell, coal or wood.
TYPES OF ACTIVATED CARBON
Coconut shell-based activated carbon
The very large internal surface areas characterized by microporosity along with high hardness and low dust make these coconut shell carbons particularly attractive for water and critical air applications as well as point-of-use water filters and respirators
- Very high surface area 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
Demand is typically high for this relatively low cost filter media for both gas and liquid applications. Coal based activated carbon has a high surface area characterized by both mesopores and micropores.
- Consistent density
- Hard materials with minimal dust generation.
- Economical
Wood based activated carbon
It produces different performance characteristics in industrial applications typically catered to with coal or coconut products.
Wood based activated carbon has a high surface area characterized by both mesopores and micropores and has excellent decolorizing properties owing to its signature porosimetry
- Relatively low density
- Renewable source of raw material
Catalytic based activated carbon
Catalytic carbon is a class of activated carbon used to remove chloramines and hydrogen sulfide from drinking water.
It has all the adsorptive characteristics of conventional activated carbons, as well as the ability to promote chemical reactions.
