Gasification of coal is performed best in bituminous coal while it is expensive in case of low rank or low grade coals. It can be a simple coal gasification, fixed bed gasification, fluidized-bed gasification, entrained-flow and molten-bath coal gasification. ... Pearson, D.E.

This Chapter is principally concerned with the major topics associated with the conversion of coal to coke. Only a limited range of coal rank i.e. the bituminous coals, produce acceptable metallurgical cokes.The history of coke making is briefly reviewed followed by description of a coke battery and the by-products of coking.

Sub-bituminous coal Sub-bituminous coal also called black lignite is a type of lower grade coal which contains 35-45 percent carbon. The properties of this type are between those of lignite, the lowest grade coal, and those of bituminous coal, the second highest grade of coal. It is primarily used as a fuel for steam-electric power …

Coking coal is used in large-scale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a more stable product. The steel industry relies on coking coal. Bituminous coal accounts for almost half of all the coal that is used for energy in the United States.

What type of coal is coking coal? Bituminous class coals of high, medium, and low volatile rank that possess these properties are called "coking" coals. High quality coking coals are in great demand by steel producers, who need these coals to make high quality coke to maximise the productivity of their blast furnace operations.
