Activated carbon derived from coal is a widely-used adsorbent known for its high surface area and porosity. The production of coal-based activated carbon involves the carbonization of coal followed by the activation process, which can be carried out using physical or chemical methods. This results in a highly porous material with a large number of active sites that can effectively adsorb a variety of contaminants and pollutants from air and water.
One of the key characteristics of coal-based activated carbon is its cost-effectiveness compared to other types of activated carbon. Additionally, coal-based activated carbon offers good adsorption properties and is suitable for a wide range of applications including water treatment, air purification, and gas separation. Due to its versatility and efficiency, coal-based activated carbon plays a significant role in various industries and environmental protection initiatives.
The production process of coal-based activated carbon involves several key steps to transform raw coal into a highly porous material with a large surface area. Initially, the coal is heated in the absence of oxygen to drive off volatile compounds and create a char residue. This char is then activated through either physical or chemical methods to increase its adsorptive properties. Physical activation typically involves exposing the char to high temperatures in the presence of a gas, such as steam, while chemical activation utilizes an activating agent, like zinc chloride, to enhance the development of pores within the material.
Following activation, the coal-based activated carbon is washed and dried to remove any impurities or residual activating agents. This thorough purification process is crucial to ensure the final product meets the required quality standards for various applications. Once the activated carbon has been thoroughly cleaned, it is typically pulverized into a fine powder or formed into granules or pellets, depending on the intended use. The final step involves packaging and distribution of the coal-based activated carbon to industries ranging from water treatment and air purification to gas adsorption and chemical processing.
Coal-based activated carbon finds widespread applications across various industries due to its excellent adsorption properties. One of the primary applications of coal-based activated carbon is in air and water purification processes.

These impurities can not only affect the performance of the activated carbon but also pose a risk in applications where high purity is crucial.
Additionally, the production of coal-based activated carbon can have negative environmental implications due to the use of coal as a primary raw material. The mining and extraction of coal can result in habitat destruction, water and air pollution, and greenhouse gas emissions. Moreover, the combustion of coal during the activation process contributes to carbon dioxide emissions, further exacerbating the environmental footprint of coal-based activated carbon production. Efforts to mitigate these environmental impacts through sustainable practices and cleaner production techniques are essential in addressing this disadvantage.
