Activated carbon is produced from coconut shells, wood, coal and other carbonaceous sources. During the activation process, pure carbon is extracted from these materials by a superheating method known as pyrolysis. Throughout the manufacturing process, samples are collected at various stages and tested for quality in our labs.

During the manufacturing process, the wood is heated, driving off water and highly volatile organic compounds (VOC). Wood temperature rises to approximately 275 C (527 F), and the VOC distillate yield increases. At this point, external application of heat is no longer required because the carbonization reactions become exothermic. At 350

Type 1. Heat for carbonisation is generated by allowing part of the wood charged to burn to provide the heat to carbonise the remainder. The rate of burning is controlled by the amount of air admitted to the kiln, pit, mound or retort. This is the traditional system used to produce most of the world's charcoal.

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 ].

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Step 4: Filling the Kiln. Further logs are placed around the spokes to form a well ventilated base for the chopped logs to be loaded onto. A rectangular chimney should be built up in the centre, above the 'fire space' and filled with partially burnt wood (par char) obtained, primarily, from previous burns.

A pencil is primarily made out of wood and graphite. The graphite is ground down and mixed with powdered clay and water to make a thick paste. This paste is then fired in a kiln. The result is a strong lead core that's difficult to break and extremely smooth for writing on paper. Rubber and aluminum are also part of a pencil's anatomy.

The Direct Method. This is perhaps the easiest way to make charcoal. The direct method is to make a fire in a container, then add wood to it. Once it is burning, you cover the container loosely with a metal sheet to restrict the air. Watch as white smoke and steam from the wood comes out of the gaps around the cover.
