Adsorbent Carbons Pvt

As explained above on the different production technique of activation, classified as Chemically activated carbon and Steam activated carbon. Adsorption is a surface phenomenon that results in the accumulation of molecules within the internal pores of an activated carbon. Almost any organic matter with a large percentage of carbon could theoretical... ly be activated to enhance its sorptive characteristics.In practice, however, the best candidates for activated carbon contain a minimum amount of organic material, have a long storage life,are hard enough to maintain their properties under usage conditions, may be obtained at a low cost, and obviously are capable of producing a high-quality activated product when processed Activated carbon are complex materials and depending upon its requirement on the end application it is grinded or moulded to different forms. Based upon its size/form , they are classified into Granular activated carbon (GAC), Powder activated carbon (PAC), Extruded activated carbon / Pellets Abrasion/Hardness Number: Relative measure of the ability of granular or pelletized activated carbon to resist at trition during handling and use. Absorption:: A process in which molecules are taken up by a liquid or solid and distributed throughout the body of the liquid or solid. Activated carbons do not absorb other materials (impurities). Activated Carbon: A family of carbonaceous materials manufactured by processes that develop an internal pore structure with adsorptive properties. Adsorption: A process in which molecules or atoms are concentrated on a surface by chemical or electrostatic (physical) forces, or both. Apparent or Bulk Density: Usually measured in g/ml or pounds per cubic foot. Bulk Density is used to determine the weight of a fixed volume of activated carbon. Chemisorption (chemical adsorption): The binding of an adsorbate to the surface of a solid by forces whose energy levels approximate those of a chemical bond. Dosage: The quantity of substance applied per unit weight or volume of the ...Read More
