metallurgical coal to have low sulphur and phosphorous contents. The coking process consists of heating metallurgical coal to around ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material – coke. Coke is produced in a coke battery which is
