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 major raw materials, auxiliary materials, energy inputs, atmospheric emissions, waterborne emissions, and waste outputs from the production process. Infrastructure such as production equipment manufacturing and plant construction is not included within the dataset's system boundary. This dataset is compiled from data from multiple sources. Coke production activities include coking, cooling, screening, and other process steps. Coke oven gas is a by-product of this process.

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 blast furnace ironmaking processes in 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, leading to a series of complex physical and chemical transformations that ultimately reduce iron oxide in the ore to metallic iron. Coke oven gas is a byproduct of this process.

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.
