Description
Coke is primarily used in the blast furnace ironmaking process in the metallurgical industry to reduce iron oxide in iron ore into metallic iron. This dataset includes key raw materials, auxiliary materials, energy inputs, atmospheric emissions, waterborne emissions, and waste generated during the production process. Infrastructure such as production equipment manufacturing and plant construction is not included within the system boundary of this dataset. The dataset is compiled from data sourced from multiple references. Coke production activities covered in this dataset include coking, cooling, screening, and related processing steps.
Activity Description
The production activity of coke includes processes such as coking, cooling, and screening.
Process Description
Coke is an important metallurgical raw material, typically produced by high-temperature carbonization of coal. It is a solid fuel with high carbon content, primarily used in the blast furnace ironmaking process within the metallurgical industry. The main component of coke is fixed carbon, with a content usually exceeding 85%, along with volatile matter and ash. Inside the blast furnace, coke reacts with iron ore at high temperatures, undergoing a series of complex physical and chemical transformations that ultimately reduce iron oxides in the ore to metallic iron.

Technology comment
Coking involves heating coal to above 1000°C under oxygen-deficient conditions, causing it to undergo pyrolysis reactions that produce coke and by-products (such as gas and tar). After coke formation, it requires cooling, screening, and quality inspection.
