Pure Hardwood Charcoal

Wood charcoal is the dark remains of burnt wood made of carbon and ash. They are often produced by the heating of wood or by pylolysis and are usually an impure form of carbon due to their ash content. Yet, hardwood charcoal is one of the purest forms of carbon available as its ash content is very minimal. Hardwoods are primarily obtained during the dry season from November to March depending on the rainfall distribution of the area. Known export destinations for hardwood include Poland, Germany, Belgium, United Kingdom and Italy.

For quality export of hardwood charcoal, they should contain considerably low ash, minimal volatile matter content with very low moisture content and not more than 2% broken pieces. They should be lumpsum (usually between 40 -120mm), dark grey and have a carbon content of not less than 70%. Generally, it is advisable to produce and process charcoal in the dry season to prevent soaking in rain which might be rejected in the market. For export, they are usually packaged in PP bags.

The benefits and uses of charcoal have been recognized since the early times and its use has increased considerably over the years. One use of hardwood charcoal, and by far the most important use, is as a metallurgical fuel.  The charcoal is the basic burning fuel used by blacksmiths and other application where strong heat is required. As a result of its high surface area, hardwood charcoal is used as an absorbent, a filter or as a catalyst.

Hardwood charcoal is also the best form of fuel available for outdoor cooking. Before the industrial revolution, it was commonly used as fuel and is still used today especially in most parts of Central and West Africa. Furthermore, charcoal is useful in the making of syngas. The syngas is basically used as fuel for chemical feedstock as well as automotive propulsion.

During periods of petroleum scarcity, automobiles have been made specifically to burn wood gas which is produced by burning wood or charcoal in wood gas generators. In 1931 an automobile was developed by Zhongming in China which was powered by hardwood charcoal.  Hardwood charcoals and sulphur are the major fuel components for making gun powders as well as other pyrotechnic materials.  They are equally used in producing carbon disulphide through sulphur vapor reaction. For this process, the hardwood is burnt at high temperatures to minimize the residues of hydrogen that results in side reactions.

Hardwood charcoal also serves medicinal purposes when consumed. Its ability to solve digestive defects and gastric problems have been recognized and for this purpose, it can be consumed in powder form, capsule or in tablet form. The industrial use of charcoal is also noted as its use is seen in iron melting. Usually, hardwood charcoal burns at an intensity of about 28000C compared to the melting point of iron which is about 1300 -15000C. This explains why hardwood charcoal is the preferred choice of material for blacksmiths when forging iron.
