Activated Carbon

We, Hir Primak Enterprise, are actively engaged in importing, exporting and supplying Activated Carbon which is a form of carbon that is activated by a carefully controlled oxidation process to develop a porous carbon structure. The imperfect structure results in a high degree of porosity and over a broad range of pore sizes, from visible cracks and crevices to gaps and voids of molecular dimensions. The specified structure of carbon gives it a very large surface area which allows the carbon to adsorb a wide range of compounds. Activated carbon has the highest volume of adsorbing porosity of any material available to mankind.

Forms of activated carbon:

Three main forms of activated carbon are

  • 1) Granular Activated Carbon - Irregular shaped particles with sizes ranging from 0.2 to 5 mm.
  • 2) Powder Activated Carbon - Carbon with a size predominantly less than 0.21mm (70 US mesh)
  • 3) Pelleted Activated Carbon - Extruded and cylindrical shaped with diameters from 0.8 to 5 mm.

Specification: CAS No. 7440-44-0

Physical Characteristics :

Hardness : The harder the activated carbon, the less it will crumble into fine particles during handling and use. High hardness levels and low dust levels. This improves material handling characteristics and is especially important where carbon fines cannot be tolerated.

Ash Content : This is the inorganic, inert, amorphous and unusable part present in the activated carbon. Lower the ash content, the better the activated carbon. The practical limit for the level of ash content allowed in the activated carbon is less than 2%.

Moisture : This is the amount of water physical bound on the activated carbon under normal condition. The practical limit for the level of moisture content allowed in the activated carbon is less than 3%.

pH Value : The pH Value of activated carbon is a measure of whether it is acidic or basic. Activated Carbon normally is specified for a pH of 9 – 11.

High surface area : up to 1400 m2/g. This allows for long life and high adsorption capacity.
