Coking coal is a coal that has been deeply buried and as a result has very specific and rare characteristics. Less than 5% of all of the coal deposits globally are coking quality, and many of these vary significantly in terms of parameters and coking qualities. West Cumbria coals are high volatile, hard coking coal. They have:
P. GoldsWorthy, ... E. On, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013. Wall pressure and battery life. During the plastic stage of the coking process swelling of the coal mass can arise due to the inability of volatile emissions to easily escape. Swelling can impart pressure to the refractory walls of the ...
The industrial production of coke from coal is called coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This process vaporizes or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coalgas and coaltar.
necessary in this process since the coal used for coke production would be a blend of Indiana and other metallurgical coals. Production of coke at mine mouth would afford a transportation savings because a large portion of coal used by the coking facility .

DELAYED COKING PROCESS. Description: Delayed coking process is a thermal process which increases the molecular aggregation or association in petroleumbased 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).

Coal, either as coal fines or as coal briquettes, is introduced into a coking chamber and is thereat exposed to microwave radiation to transform the coal into hot coke. Preferably, the microwave radiation is at a frequency of from twenty to 3000 MHz. The hot coke is then passed to a cooling zone whereat photocells absorb radiant energy from the hot coke and transform the thus absorbed radiant ...
