giving a coal its properties, as indicated by a standard suite of tests. Quality is normally considered in the context of coal’s potential utilisation and how it might favourably or unfavourably affect the utilisation process. Rank (Coal) Rank is a concept that describes the degree of coalification (physical and chemical transformation from vegetable material to coal) that has been achieved coalification – has an important bearing on its physical and chemical properties and is referred to as the ‘rank’ of the coal. Low rank coals, such as lignite and sub-bituminous coals are typically softer, friable materials with a dull, earthy appearance. They are characterised by high moisture levels and low carbon content, and therefore a low energy content. Higher rank coals are
coal and its properties pdf

Sub-bituminous coal, whose properties range between those of lignite and those of bituminous The energy density of coal, that is its heating value, is roughly 24 megajoules per kilogram (approximately 6.7 kilowatt-hours per kg). For a coal power plant with a 40% efficiency, it takes an estimated 325 kg (717 lb) of coal to power a 100 W lightbulb for one year. 27.6% of world energy was. Due to its relatively high carbon content and solid, easily-handled form, coal is used for fuel, and has been for hundreds of years. As a fuel, coal is the largest source of energy for the generation of electricity worldwide..
“Efficient and Large Scale Synthesis of Graphene from Coal”.
Carbon is unique among the elements in its ability to form strongly bonded chains, sealed off by hydrogen atoms. These hydrocarbons, extracted naturally as fossil fuels (coal, oil and natural gas), are mostly used as fuels. A small but important fraction is used as a feedstock for the petrochemical industries producing polymers, fibres, paints, solvents and plastics etc. Impure carbon in the.
