About coke and semi-coke; of coal, lignite or peat, whether or not agglomerated; retort carbon
HS code 270400 covers the production of coke and semi-coke, which are essential materials in various industrial processes. Coke, a solid carbon-rich material, is primarily derived from the high-temperature pyrolysis of coal. It is a crucial input for the steel industry, serving as a reducing agent and fuel source in blast furnaces. The production and trade of coke and semi-coke play a significant role in the global energy and manufacturing sectors, contributing to the overall economic development.
Production process
The production of coke and semi-coke involves the heating of coal or other carbonaceous materials, such as lignite or peat, in the absence of oxygen. This process, known as pyrolysis or carbonization, drives off volatile components, leaving behind a solid, porous material rich in carbon content. The specific techniques used in this industry include charging the raw materials into coke ovens, controlling the temperature and duration of the heating process, and carefully managing the cooling and handling of the final coke or semi-coke product.
Production inputs
The main inputs required for the production of coke and semi-coke include various types of coal, lignite, or peat as the primary raw materials. Additionally, the industry relies on specialized equipment, such as coke ovens, conveyor systems, and material handling machinery, to facilitate the production process. Energy sources, such as electricity or natural gas, are also necessary to power the high-temperature pyrolysis and other operational requirements.
Production outputs
The primary outputs of this industry are coke and semi-coke, which are then consumed by other industries. Coke is widely used as a reducing agent and fuel in the 720110 Pig iron and 720211 Ferroalloys industries, as well as in the production of 271011 Motor spirit, including aviation spirit and 271019 Other light oils and preparations. Semi-coke, a less processed form of coke, may also find applications in various industrial sectors, depending on its specific properties and characteristics.
