What Is Metallurgical Coke? | Sciencing

Coke is created by heating metallurgical coal to around 2,000 degrees Fahrenheit. The coking process takes about 12 to 36 hours in the oven to complete, according to the World Coal Association. After being taken out of the oven, the coke is cooled with water or air to before it is either placed into storage or is put directly to the blast furnace.

Coal gas - Wikipedia

Gasification is the process of subjecting a feedstock to chemical reactions that produce gas. The first process used was the carbonization and partial pyrolysis of coal. The off gases liberated in the high-temperature carbonization of coal in coke ovens were collected, scrubbed and used as fuel.
