What is coking coal, and where is it used?
Metallurgical or coking coal is a primary ingredient in the steel making process. More than two-thirds of global steel is produced in basic oxygen blast furnaces. China is the largest consumer of premium coking coal in the world. Coking coal, generally known as metallurgical coal, is a naturally occurring sedimentary rock. When heated, coking ...

Coking Coal
Coking coal must also have low sulfur and phosphorous contents. The coking process takes place over long periods of time—between 12-36 hours in coke ovens. The heat is transferred from the heated brick walls into the coal charge. From about 375°C to 475°C, the coal decomposes to form plastic layers near each wall.
Coking - an overview | ScienceDirect Topics
Description: Delayed coking process is a thermal process which increases the molecular aggregation or association in petroleum-based residues or coal tar pitches leading to extended mesophase domains. This is achieved by holding them at an elevated temperature (usually 750 K–765 K) over a period of time (12 to 36 h).

Commodity Coal - Everything you need to know about Coal
Coking coal is used to produce coke, which in turn is used to produce pig iron. The commodity coal used for energy generating is declining due to an increase in the use of natural gas and nuclear power. The overall coal production however is increasing, for other purposes. There are a number of reasons for the increased production and ...

Fig 1 Types of coal and their uses. The term 'coking coal' is used to designate certain types of bituminous coals which, when heated at high temperatures (over 1,000 deg C) in the absence of air (carbonization), soften, liquefy, and then re-solidify into a hard but porous mass known as coke, used mainly in the production of hot metal in a blast furnace.

of coal which is used for determining of coking coal is the petrographic analysis & reflectance. The coking coal should have a minimum of 60% virtrain (active constituents) and maximum of 40% Inertinite (non—reactive constituent). For finding out the physical strength of the coke, reflectance studies on coking coal is also done.
