how coke is made from coal - Lisbdnet.com

How Coke Is Made From Coal? Coke is produced by heating coal at high temperatures, for long periods of time.This heating is called "thermal distillation" or "pyrolysis." In order to produce coke that will be used in blast furnaces, coal is usually thermally distilled for 15 to 18 hours, but the process can take up to 36 hours.

What is the Best Coal for Coke Making

Probably the most satisfactory method of determining the suitability of a coal for making coke of required quality is to make a full-scale oven test in which are maintained the carbonizing conditions under which it is proposed to use the coal. The coke-plant operator ordinarily will use this method as a final check on results of small-oven ...

Firstly coal is converted to lump coke in a coking oven. A particular rank of coal, known as "coking coal", is required to make the preferred quality of coke. Then raw iron is made by reducing (removing the oxygen from) iron ore (iron oxide) by reacting it at high temperature with coke in a blast furnace.

How does coke and coal play into steel making? - FedSteel.com

In either coke or non-coked coal, the quality of the coal affects the quality of the steel. Metallurgical coke is made from bituminous coals by a distillation process. Ash deposited by the coal must be kept to a minimum, preferably below 10% of the original mass. The ash can lower furnace temperatures and leave non-combustible materials.

Ammonia is recovered as an aqueous solution or as an ammonium sulfate salt. Napthalene, an important poly-cyclic aromatic chemical is also distilled from coke gas and tars.

Coking | Article about Coking by The Free Dictionary

Coking in a coke oven takes place in layers, in which case the layer temperature decreases from the heated oven walls (above 1000°C) toward the center of the charge. The layer composition also changes in the same direction (starting at the wall), from coke through semicoke, coal in the plastic state, and dry coal to raw coal.
