Coal utilization - Carbonization (coke making)

Coke is the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature out of contact with air. The process of heating coal in this manner is referred to as carbonization or coke making. High-temperature carbonization, with which this section is concerned, is practiced to produce a coke

12.2 Coke Production - US EPA

2015-9-10  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".

How does coke and coal play into steel making? -

2016-6-22  Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880’s, steel was produced using charcoal.

Do we really need coal to make steel? – Wildsight

2020-6-1  From there, the coal is converted into coke and then used in the blast furnace-basic oxygen steelmaking process. Coal does three things in this process: it is burned to supply the huge amounts of heat required, it supplies gases to strip oxygen from the iron ore and roughly 1% of the coal ends up as carbon in the steel.
