Description
Coking refers to a process in which coking coal is heated to about 1000°C under air-isolated conditions (high-temperature carbonization), producing coke, coke oven gas, and other coking chemical products through thermal decomposition and coking. This process represents the coking of 1 kg of coking coal, yielding 0.753 kg of coke. This process should be used together with the production data of 1 kg of coking coal. The life cycle inventory is compiled from data of multiple sources.
Activity Description
The coking process includes coal preparation, coking,煤气 purification, and product recovery. This dataset includes energy consumption, auxiliary material consumption, by-products or waste generated, atmospheric emissions, and waterborne emissions from the coking process.
Process Description
Coking refers to the process where coking coal is heated to approximately 1000°C (high-temperature carbonization) in the absence of air, resulting in the thermal decomposition and coking to produce coke, coke oven gas, and other coking chemical products. This process represents the coking of 1 kg of coking coal, yielding 0.753 kg of coke. This process should be used together with the production data of 1 kg of coking coal.

Technology comment
Coking refers to the technological process of separating and converting low-volatile, high-volatile components and fixed carbon in coking coal into coke through specific heating, distillation, and cooling processes. Coking technology is one of the key production processes in the iron and steel industry. The coke obtained from high-temperature coking can be used as a raw material or fuel in blast furnace smelting, casting, and chemical production. The distilled coke gas generated during the coking process, after recovery and purification, can serve as a raw material for the production of synthetic fibers, pharmaceuticals, and fuels.
