In the process of transformation (coalification), peat is altered to lignite, lignite is altered to subbituminous, subbituminous coal is altered to bituminous coal, and bituminous coal is altered to anthracite. Lignite is the lowest rank of coal which means that it has the lowest heating value and lowest carbon content. Although lignite ...

Coal is important particularly because of the two reasons: steel production and electrical energy. Coal is giving about 23% of the world's total primary energy. 38% of the world's generated electrical energy is gained from coal. For 70% of the world's steel production, coal is needed as the key ingredient.
Metallurgical coal. Metallurgical coal is used in steel production and is the focus of our operations and projects. Thermal coal. Thermal coal, also produced by our operations, is used to generate heat and power in thermal power plants.
Gasification: Any process by which solid coal is converted to a gaseous fuel. Lignite: Brown coal; a form of coal with ... iron and steel production, and chemical manufacture for heating and for steam generation. Another use for coal is in the manufacture of coke. Coke is nearly pure carbon produced when soft coal is heated in the absence of air.
Coal production accelerated (+%), in line with China's output rebound (+%) China, the world largest producer of coal and lignite (45%), relaxed production restrictions in 2017 and raised its domestic production after three years of decline, contributing to half of the global increase in coal production.
production of synthesis gas. Coal can be a cheap feedstock to produce synthesis gas though the gasification process. However, coalderived synthesis gas production is generally not the dominant process on an industrial scale when natural gas is available. There is a technical challenge in decreasing the capital investment and the operating cost to
