Kinetics of Reaction between Iron Ore Fines and Coal or ...

Iron ore fines and coal fines can be made to react to produce direct reduced iron (DRI) fines. There are three ways to achieve the reactions, namely, (a) using homogeneous mixtures, (b) arranging the ore and coal fines in separate but adjacent layers and (c) by fluidizing a mixture of iron ore fines and coal fines by air. This paper mainly discusses the work done by the author and his ...

2020-05-21  The second way to produce iron is through direct ore reduction using gas. Syngas and natural gas have long been used in these processes, but the focus has now shifted to the use of hydrogen, which offers near-zero Scope 1 emissions. However, at the moment it is a trade-off with higher Scope 2 emissions from hydrogen produced from natural gas.

In this process, ore fines and coal are manipulated to melt iron ore. In 1993, the process could produce eight tons of iron ore per hour using ore directly in the smelter. Process modifications are expected to increase the efficiency to 14 tons per hour. Commercial feasibility studies were performed in 1995.

Coke (fuel) - Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
