Coal Composition - an overview ScienceDirect Topics

Coal Composition. Coal compositions span a wide continuum that is conventionally divided into four classes by gravimetric energy and carbon content (in decreasing order): anthracite, bituminous, sub-bituminous and lignite. From: Renewable and Sustainable Energy Reviews, 2016. Related terms: Gasification; Coal Bed Methane; Syngas; Flue Gas; Sulfur

Coal, a naturally occurring combustible solid, is one of the world's most important and abundant energy sources. From its introduction 4,000 years ago as a fuel for heating and cooking, to its nineteenth- and twentieth-century use in generating electricity and as a chemical feedstock , coal, along with oil and natural gas, has remained an important source of energy.
