Several types of coal may be blended,12.2 Coke Production - US EPA,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. Metallurgical coke is used in iron and steel industry processes (primarily in blast furnaces) to reduce iron ore to iron. Over 90,Coke Manufacturing - IFC,In the coke-making process, bituminous coal is fed (usually after processing operations to con-trol the size and quality of the feed) into a series of ovens, which are sealed and heated at high temperatures in the absence of oxygen, typically in cycles lasting 14 to 36 hours. Volatile com- pounds that are driven off the coal are collected and processed to recover combustible gases and other by,
