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

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.

Biocoal, also commonly referred to as syn coal (synthetic coal), is created through the torrefaction of biomass. Biomass is a broad term that covers plant products and byproducts. From forest product residuals to sugarcane bagasse, the term biomass is used to describe anything with a cellulosic structure. And while biomass itself is used as a ...

By the 18th century, the availability of wood for making charcoal had limited the expansion of iron production, so England became increasingly dependent on Sweden (from the mid17th century) and then from about 1725 on Russia for the iron required for industry. Smelting with coal (or its derivative coke) was a longsought objective.

Planing: Smoothing the surface of each lumber piece and making its width and thickness uniform. Grading: The process of assessing the characteristics of each lumber piece in order to assign its "grade" (quality). The success of wood manufacturing rests on the mill's ability to retain the wood's quality throughout the manufacturing process.

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.

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.

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.

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.
