Carbon comes in two forms: charcoal and activated charcoal, both of which are often employed for several applications. Despite the fact that they both come from carbon-rich materials, they differ greatly from one another. The key distinctions between charcoal and activated charcoal will be covered in this article.
Charcoal: What is it?
Burning organic materials like wood, peat, coconut shells, or sawdust without oxygen produces charcoal, a dark, porous substance. The organic material is subjected to a process called pyrolysis that eliminates water, volatile substances, and other impurities, leaving behind a highly carbonized product. For ages, people have used charcoal as a fuel for heating and cooking, as well as for various commercial and creative uses.
Charcoal's Uses
There are various uses for charcoal nowadays. Metallurgy and cooking are two of charcoal's best-known applications. Because of its porous structure, charcoal is also utilized for water and air filtration. Charcoal with little or no sulfur content is the most efficient variety for metallurgy. This is due to the fact that whatever metal is burned by the charcoal typically ends up absorbing sulfur.
Activated charcoal: What is it?
On the other hand, activated charcoal is a type of extremely porous charcoal that has been given an oxygen treatment to expand its surface area and make it more adsorbent. Charcoal is heated to a high temperature during the activation process, and thereafter it is exposed to an oxidizing agent such as steam or carbon dioxide. Due to the formation of a network of tiny holes and fissures as a result, the surface area and molecular-trapping capacity of the charcoal are considerably increased.
Although activated charcoal is a good filter, it can accumulate so many impurities that there are no longer any pores or binding sites for new impurities to attach to. As a result, activated charcoal might lose its potency after several applications, necessitating the production of new activated charcoal.
Differences: activated charcoal as well as charcoal
The porosity of charcoal and activated charcoal is one of their most notable characteristics. In comparison to activated charcoal, which may have a surface area of up to 1500 square meters per gram or more, charcoal has a comparatively modest surface area, often between 300 and 500 square meters per gram. Because of its larger surface area, activated charcoal is far more efficient at adsorbing gases, poisons, and other environmental pollutants.
The purity of the two types of carbon is a significant distinction as well. Charcoal is generally made from a range of organic sources, some of which may be contaminated with tar, ash, or other impurities. Contrarily, activated charcoal is typically produced using high-purity carbon sources like bamboo or coconut shells, leading to a product that is cleaner and more reliable.
When it comes to applications, charcoal is mostly employed as a fuel source for industrial activities like heating and cooking. Additionally, it is employed as a sketching medium in the arts and as a poisoning or overdose remedy in medicine. On the other hand, activated charcoal has a wide range of uses, including soil remediation, water filtration, air purification, medicinal treatments such as the elimination of gas and odors, and as a digestive aid.
