What is Activated Carbon?

activated carbon img1Activated Carbon is a form of carbon that is activated by a oxidation process to develop a porous carbon structure. By thermal decomposition in a furnace using a controlled atmosphere and heat, the carbon raw material is converted to activated carbon. The raw material used for activated carbon is coal, wood, peat, coconut shell.



About Charcoal and Activated Carbon

Charcoal img2Charcoal can be quite effective at removing some tastes, odours, and colour. Ordinary charcoal available locally could be used, but activated carbon is more effective. The charcoal is not regularly renewed or if the filter is left unused for some time. Activated carbon have a porous surface which traps microscopic particles and large organic molecules. Activated carbon bits cannot be reused and need to be replaced after filtering about 150L of water.

Charcoal is commonly used in the home. It's used in water treatment systems, in vacuum cleaners, for creating works of art, and for cooking barbecues. Most of us are familiar with charcoal, and have used it at some time. Charcoal is versatile and is used for to remove chlorine from water, to remove odors, to draw with and to cook with.

Activated carbon, has oxygen added to it to increase its porosity, thereby, adding to its surface area. It's normally used to remove chemicals, toxins, and gases. Due to its added benefits, activated carbon has replaced charcoal in water purification systems and fish tank filtering systems. Where toxins are to be removed, activated carbon has proven to be more successful.

Forms of Activated Carbon

1. Granular activated carbon (GAC)

Irregular shaped particles with sizes ranging from 0.2 to 5 mm. This type is used in both liquid and gas phase applications


2. Extruded or Pelletised Activated Carbons

Extruded and cylindrical shaped with diameters from 0.8 to 5 mm. These are mainly used for gas phase applications because of their low pressure drop, high mechanical strength and low dust content.


3. Powdered Activated Carbons (PAC)

Pulverized carbon with a size predominantly less than 0.18mm (US Mesh 80). These are mainly used in liquid phase applications and for flue gas treatment

4. Water Wash/ Acid Wash and High Purity Activated Carbon.

Ph range of 6 to 8 used for water purification and drinking water treatment.

Properties of Activated Carbon

There are wide variety of activated carbon with exhibits different characteristics depending upon the raw material and activation technique used in their production. Understanding both Absorptive and Physical characteristics of the material is very important in the selecting an activated carbon.

Adsorptive Characteristics

Surface area (BET N2) - measurement, using nitrogen (N2), of the extent of the pore surface developed within the matrix of the activated carbon. Used as a primary indicator of the activity level, based on the principle that the greater the surface area, the higher the number of adsorptive sites available.

Pore size distribution - determination of the pore size distribution of an activated carbon is an extremely useful way of understanding the performance characteristics of the material. The International Union of Pure and Applied Chemistry (IUPAC) defines the pore size distribution as:
Micropores r < 1nm
Mesopores r 1-25nm
Macropores r > 25nm

The macropores are used as the entrance to the activated carbon, the mesopores for transportation and the micropores for adsorption.

Iodine number - measurement of the porosity of an activated carbon by adsorption of iodine from solution.
Carbon tetrachloride activity - measurement of the porosity of an activated carbon by the adsorption of saturated carbon tetrachloride vapour.

Physical Characteristics

Hardness - an important factor in system design, filter life and product handling. There are large differences in the hardness of activated carbons, depending on the raw material and activity level.
Bulk Density - should be carefully considered when filling fixed volumes as it can have considerable commercial implications.
The backwashed and drained density will show a lower value due to the water film between the particles of activated carbon.
Particle size distribution - the finer the particle size of an activated carbon, the better the access to the surface area and the faster the rate of adsorption kinetics. In vapour phase systems this needs to be considered against pressure drop, which will affect energy cost.
Careful consideration of particle size distribution can provide significant operating benefits.
The important properties of activated carbon relevant to specific applications are considered further in the text.

Manufacturing Process

We manufacture activated carbon using Steam Activation.

Process of Steam Activation

The process of activation is carried out in two stages. First the coconut shell is converted into shell charcoal by carbonization process which is usually carried out in mud-pits, brick kilns and metallic portable kilns. The coconut shell charcoal is activated by reaction with steam at a temperature of 900oC - 1100oC under controlled atmosphere in a rotary kiln. The reaction between steam and charcoal takes place at the internal surface area, creating more sites for adsorption. The temperature factor, in the process of activation is very important. Below 900oC the reaction becomes too slow and is very uneconomical. Above 1100oC the reaction becomes diffusion controlled and therefore takes place on the outer surface of the charcoal resulting in loss of charcoal.
