Coal gasification - Wikipedia
Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before ...
12.2 Coke Production - US EPA
12.2 Coke Production 12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.
COKE PRODUCTION FOR BLAST FURNACE IRONMAKING
result in lower coke rate, higher productivity and lower hot metal cost. COKE PRODUCTION The cokemaking process involves carbonization of coal to high temperatures (1100°C) in an oxygen deficient atmosphere in order to concentrate the carbon. The commercial cokemaking process can be broken down into two categories: a) By-product Cokemaking

Deliveries of coal to coking plants and coke oven coke production Hard coal (more specifically coking coal) is essential to produce coke oven coke for the steel and iron industry. The latest available annual figures show that in 2017 coking plants in the EU consumed 51 million tonnes of coking coal to produce 39 million tonnes of coke oven coke, keeping a similar level to 2016 (see Figure 6).
What You Should Know About Metallurgical Coal
Metallurgical coal differs from thermal coal, which is used for energy and heating, by its carbon content and its caking ability. Caking refers to the coals ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces.

In a second step the production will be doubled. Thus an increase in the output of about 350% will be obtained within 15 years. CONCLUSIONS A coking plant should produce coke at the lowest production costs pos- sible, meeting completely the quality requirements of the customer. The main cost factor of coke production is the price of the coal.
