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.

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.

The manufacturing process for "synthetic fuel gases" (also known as "manufactured fuel gas", "manufactured gas" or simply "gas") typically consisted of the gasification of combustible materials, usually coal, but also wood and oil. The coal was gasified by heating the coal in enclosed ovens with an oxygenpoor atmosphere.

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.

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.

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.
