what chemicals is coal made of
Crude coal tar is a raw material which is further distilled to produce various carbon products, refined tars and oils used as essential components in the production of aluminum, rubber, concrete, plasticizers, coatings and specialty chemicals.oke is uses as a fuel and as a reducing agent in smelting iron ore in a blast furnace to manufacture steel and in foundry operations. Crude coal tar consists of a mixture of naturally occurring compounds containing hydrogen and carbon that are common to all organic fuels including coal, petroleum and wood.
The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.oal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010 (7.99 billion short tons) and is expected to increase 48% to 9.05 billion tonnes (9.98 billion short tons) by 2030.
