We Are Kalimati

Developer and supplier of high grade activated carbon used in a wide of industrial applications.

Gas Phase Adsorption

Activated Carbon is widely used in the treatment of air and gas in order to capture toxic air pollutants (primarily Volatile Organics Compounds, or VOC) from petrochemical plants, landfill sites, manufacturing operations, and chemical processing facilities. Selective adsorption is achieved by impregnation of activated carbon with certain chemicals.

Liquid Phase Adsorption

For water & liquid treatment including municipal, industrial waste water, sewage water and process liquids which contain a wide range of organic and inorganic pollutants, Activated carbon adsorbs these pollutants from the waste in a liquid phase, acting as the optimum purification solution.

Application Field


What is activated Carbon

  • Activated carbon

    Activated carbon is a carbonaceous adsorbent with a high internal porosity, and hence a large internal surface area. The manufacturing and activation process and the basic raw materials used have a determining influence on the adsorptive capacity of activated carbon products in use. Raw material may be charcoal, bituminous coal, wood, coconut shells, olive stones, fruit stones, peat etc.

  • Properties of Activated Carbon

    Commercial activated carbon grades have an internal surface area of 500 up to 1500 m2/g. Related to the type of application, three major product groups exist:

    Powdered activated carbon; particle size 1-150 μm
    Granular activated carbon, particle size 0.5-4 mm
    Extruded activated carbon, partilce size 0.8-4 mm

    A proper activated carbon has a number of unique characteristics: a large internal surface area, dedicated (surface) chemical properties and good accessibility of internal pores. According to IUPAC definitions three groups of pores are distinguished

  • Why are Activated Carbons Different?

    Macropores (> 50 nm diameter)
    Mesopores (2-50 nm diameter)
    Micropores (< 2 nm diameter)

    Micropores generally contribute to the major part of the internal surface area. Macro and mesopores can generally be regarded as the highways into the carbon particle, and are crucial for kinetics. Macropores can be visualised using scanning electron microscopy. The pore size distribution is highly important for the practical application; the best fit depends on the compounds of interest, the matrix (gas, liquid) and treatment conditions. The desired pore structure of an activated carbon product is attained by combining the right raw material and activation conditions.
