Production and Use of an Activated Carbon
Production of Activated Carbon Activated carbon can be made from a variety of sources, including hard coal (anthracite coal), coconut shells, brown coal, and wood. Activated carbon is typically produced using the steam activation process for cost reasons. The raw material is activated by hot steam under a vacuum in a furnace at temperatures ranging from 900 to 1100 °C during this process. The material cannot burn because there is no oxygen present. Instead, the heat significantly increases the internal surface of the material. This activated carbon can then be processed for a variety of applications. What is the Function of the Activated C arbon Powder ? The manufacturing of activated carbon has different adsorption properties depending on the carbon type used. Odour molecules are trapped inside the activated carbon structure and organic compounds are adsorbed once air passes through the carbon filter. See the yellow marks in the diagram above. The airflow also reduces the capacity of...
