Activated Carbon: An Essential Product for Purification
Activated carbon is a highly effective material that has been used for purification processes for over a century. It is produced from carbon-rich materials such as coal, carbon and charcoal (see more about charcoal production for activated carbon).
The cost of setting up an activated carbon manufacturing plant can vary depending on the activation furnace type, size of the plant, the type of raw materials used and the production capacity. However, with the increasing demand for activated carbon, investing in a manufacturing plant can be a lucrative opportunity.
Activated carbon is used in a wide range of applications, including of industry such as: water treatment, Air Purification, Food and Beverage Industry, Medical Industry, Chemical Industry, Mining and Metallurgical Industry, Environmental Remediation, Personal Protective Equipment. Activated carbon is also used in bulk quantities for various industrial processes, including the purification of natural gas, the removal of impurities from industrial wastewater, and the production of pharmaceuticals. Activated carbon pellets, granulated activated carbon, and activated carbon powder are commonly used in these industrial applications (see more about MAIN CATEGORIES OF ACTIVATED CARBON and SCOPES OF ITS APPLICATION)
With the increasing demand for purified air and water, investing in an activated carbon manufacturing plant can be a profitable opportunity.
GreenPower offers to supply, proven since 2004, horizontal rotary furnaces and vertical multi-stage reactor of high quality Korean production, for the activated carbon production or regeneration.
Adsorption occurs by a chemical reaction using high temperature with direct contact of superheated steam and charcoal from the shells of various nuts or wood, or it is possible activation of black coal, anthracite, brown coal, peat, etc. Also it is possible to use the multistage reactor for the regeneration of used activated carbon. Depending on the raw materials parameters, time and temperatures of activation reaction, will depend on the quality of activated carbon, which determines classification of them.
ACTIVATION CARBON PROCESS DESCRIPTION
Steam activation is a widely used method for producing high-quality activated carbon. This process involves heating carbonaceous materials, such as charcoal or natural coal, in the presence of superheated steam to create a highly porous, high surface area material that exhibits specific adsorption and/or catalytic properties.
The steam activation process is typically carried out in a rotary furnace or a multistage reactor. The carbonaceous material is first dried to remove any moisture, and then it is heated to a high temperature, typically around 800-1000°C, in the presence of superheated steam. The high temperature and superheated steam cause the carbonaceous material to undergo a series of reactions that create pores and increase the surface area of the material.
The pore structure of the activated carbon produced through steam activation is highly dependent on the activation time, temperature, and steam flow rate. Longer activation times and higher temperatures generally result in activated carbon with larger pores and lower surface
Before activation process, most important to obtain a high quality charcoal. Nuts shells are one of the mostcommonly used raw materials due to their high density and abundance, but other materials such as wood,peat and coal can also be used. This is most important raw materials for high quality charcoal production, as basis of activated carbon production: Coconut shell, Walnut shell, Hazelnut shell, Bamboo, Palm kernel shell, Pistachio shells.
Steam activation can be used to produce activated carbon with a wide range of properties, making it aversatile method for producing materials for specific applications. For example, activated carbon producedthrough steam activation can be impregnated with chemicals such as silver or copper to enhance its antibacterial properties, or it can be impregnated with chemicals such as iodine or chlorine to enhance its adsorption properties.
