Coke and semi-coke of coal, of lignite or of peat; retort carbon

CPC v2.1 Code: 331

About coke and semi-coke of coal, of lignite or of peat; retort carbon

cpc code 331 covers the production of coke and semi-coke, which are essential materials in various industrial processes. Coke, a solid carbonaceous material derived from the destructive distillation of coal, is a crucial input for the 2410 Basic Iron and Steel industry, where it is used as a reducing agent and fuel 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, lignite, or peat in the absence of air, a process known as carbonization or pyrolysis. This process drives off volatile matter, leaving behind a solid, porous material rich in carbon content. The specific techniques used in this industry include coke ovens, retorts, and other specialized equipment designed to control the temperature, pressure, and atmospheric conditions during the carbonization process.

Production inputs

The main inputs required for the production of coke and semi-coke include various types of coal, lignite, and peat, which serve as the primary raw materials. Additionally, the industry relies on specialized machinery and equipment, such as coke ovens, retorts, and other processing units, as well as energy sources to power the production facilities.

Production outputs

The primary outputs of cpc code 331 are coke and semi-coke, which are then consumed by other industries, such as 2410 Basic Iron and Steel, 2011 Manufacture of industrial gases, and 2012 Manufacture of dyes and pigments. Coke is a crucial input for the production of iron and steel, while semi-coke and retort carbon find applications in the manufacture of industrial gases and various chemical products.
