When coal undergoes a process known as destructive distillation, it converts to coke.
The steel industry uses coal coke to smelt iron ore into iron to make steel. The high temperatures created by burning coal coke give steel the strength and flexibility needed for bridges, buildings, and automobiles.
Princeton is a coal mine in west virginia that specializes in surface and underground mining of coal to produce coke and pulverized coal injection (pci) coal. It is a 12,000 square foot facility with an annual production capacity of five million tons. Princeton primarily serves coke facilities, steel mills and utility markets.

Coal action network aotearoa (cana) is committed to opposing all new coal mines in order to meet that target. However, 60% of solid energy’s coal production in nz is for steel making, mainly for export, and the company says that “there is no way of making new steel without coal”.
Metallurgical coal (also called met coal) is an important raw material used in the steel-making process, although very small amounts of coal (relative to the amount used for electricity) are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°f (1,125°f), until most of its volatile matter.
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. The unqualified term coke usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking.
In the production of coal coke in a coke oven, a byproduct of it is creosote oil which is stored in the coke oven itself. However, if full, the production of coal coke will stop and so it is recommended that the oil is pumped out into a tank for continuous production. Coal coke is also able to produce 16000 eu in a generator, 4 times the amount.
3 million tons in 1880 to a peak of forty million tons in 1916. This enormous growth had vast ramifications for southwestern pennsylvania. Thousands of workers, many of them immigrants from eastern and southern europe, flowed into the region and provided cheap labor for mines and coke works.

A process and plant for producing metallurgical coke is disclosed. The process comprises rapidly drying coal particles in an inert atmosphere, and maintaining the particles, once dry, in an inert atmosphere. The dried particles are then compressed into a briquette without addition of a binder.
The process consists of thermal decomposition of coals either in the absence of air or in controlled atmosphere to produce a carbonaceous residue known as coke. Carbonization of coal can be carried out at the following three.
Production normally takes place in a coke battery located near an integrated steel mill. Coal is loaded into the ovens and heated in the absence of oxygen up to temperatures around 1,100 degrees celsius (2,000 degrees fahrenheit).
Coking coal is converted to coke by driving off impurities to leave almost pure carbon. It is then ‘purified’ or ‘carbonised’ in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºc in the absence of oxygen for 12-36 hours.

As for the us, while the surge in light shale oil production in recent years has resulted in a drop off in gpc production, new low sulphur policies in china and winter closures to reduce air pollution have also resulted in significantly lower production of both calcined pet coke and coal tar pitch, creating market deficits and higher prices.
Production of coal fines in coke making has lately become a problem worth addressing due to its negative impact on ecosystems. The use of coal fines is becoming an issue due to high quinoline insoluble formation during the carbonisation process as well as carry over or enhancement of carbon deposition in the upper parts of the coke ovens.

Thus, growth in steel production positively impacts met coal producers such as walter energy and alpha natural resources met coal is converted to coke (almost pure carbon) by driving out impurities.
Smelting with coal (or its derivative coke) was a long-sought objective. The production of pig iron with coke was probably achieved by dud dudley in the 1620s, and with a mixed fuel made from coal and wood again in the 1670s. However this was only a technological rather than a commercial success.

The coal gas and coal water fuse together with carbon and the remaining ash, forming a hard residue commonly referred to as coke.
In the gas industry, however, the coke was the by-product, and the economics of gas production depended on heating the coal only to the point where the diminishing yield of gas no longer justified further heat treatment. The result was a coke which still contained some volatile matter, and significant amounts of sulfur and nitrogen.
