A carbonaceous substance can be used as the raw material for activated carbon. Materials for activated carbon in use worldwide are as follows: Powdered activated…
Activated carbon adsorbs. The chemical process of absorption is commonly compared to a sponge soaking up water. The water is fully integrated into the sponge,…
Activated carbon is the major adsorbent in global adsorbent market occupying more than 65% of the volume market share due to its high adsorption capacity…
Porous carbons containing several types of inorganic impregnate such as iodine, silver, cations such as Al, Mn, Zn, Fe, Li, Ca have also been prepared…
Bead activated carbon (BAC) is made from petroleum pitch and supplied in diameters from approximately 0.35 to 0.80 mm. Similar to EAC, it is also noted for its…
Extruded activated carbon combines powdered activated carbon with a binder, which are fused together and extruded into a cylindrical shaped activated carbon block with diameters…
Granular activated carbon (GAC) has a relatively larger particle size compared to powdered activated carbon and consequently, presents a smaller external surface. Diffusion of the…
Normally, activated carbons are made in particulate form as powders or fine granules less than 1.0 mm in size with an average diameter between 0.15 and…
Applications are divided broadly into two groups: air/vapor filter and water/fluid filter applications. Air and vapor filters tend to use the larger sizes of GAC,…
Virgin activated charcoal is the original product that has never been used. All the activated charcoal sold by BuyActivatedCharcoal.com is virgin activated carbon. Reactivated charcoal…
Most people have a misunderstanding that there is a difference between activated carbon and activated charcoal. Both of these terms can and are used interchangeably.…
Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical absorption. Activated Carbon is…
Mesh Size The physical size, or mesh size, of a carbon must be considered in relation to the flow rate in the system it is…
There is a relationship between BET surface area and CTC adsorption and this is taken into account when specifications are formulated. CTC activity, density and…
The hardness and resistance to attrition of activated carbons is becoming more and more important. The loosely applied term of “hardness” is somewhat difficult to…
The internal surface area of a carbon is usually determined by the BET method (Brunauer, Emmett and Teller).This method utilizes the low-pressure range of the…
The most widely used method is to measure the carbon’s capacity to adsorb carbon tetrachloride (referred to as CTC) and express this as a w/w…
The use of steam for activation can be applied to virtually all raw materials. Steam activation is the most widely used process to activate carbonaceous materials.…
Chemical activation is generally used for the production of activated carbon from sawdust, wood or peat. The process involves mixing an organic chemical compound with…
