Most of the literature refers to the production of active carbons from coal, bamboo [7,8,9,10] and other lignocellulosic materials [11,12,13,14]. Activated carbon is the most widely used adsorbent because of its low cost, exceptionally high porosity, tuneable pore size and high adsorptive capacities [ 15, 16 ].

Current Charcoal Production . Much like the old process, the modern commercial charcoal process is to heat wood with little or no air present which takes special but simple equipment. In the United States, wood is the primary material used for charcoal and is generally procured in the form of residue from sawmills slabs and edgings. Sawmills love to find users of this material because of ...

History The production of wood charcoal in locations where there is an abundance of wood dates back to ancient times. It generally begins with piling billets of wood on their ends to form a conical pile. Openings are left at the bottom to admit air, with a central shaft serving as a flue. The whole pile is covered with turf or moistened clay.

Introduction: Charcoal is made by heating wood or other organic materials above 400° C (750° F) in an oxygenstarved environment. The process, called pyrolysis, is exothermic meaning it gives off heat once started. The more volatile elements in the wood, such as hydrogen, oxygen, and some carbon, combine to form gasses that escape from the wood.
