The recovery of coal chemicals is an economical necessity, as they equal approximately 35 percent of the value of the coal. To produce quality metallurgical coke, a hightemperature carbonization process is used. Hightemperature carbonization, which takes place above 900°C (1650°F), involves chemical conversion of coal into a mostly gaseous ...

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
