Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
HIGH GRADE ANTHRACITE Hard, compact variety of carbon similar to graphite. It is low in contaminates and has the highest calorific content of all types of coal. High grade anthracite accounts for less than 0.05% of global..
Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. Coking coal must also have low sulphur and phosphorous contents.

Found in sedimentary strata . Contains carbon, volatile matter, moisture and ash Mostly used for power generation and metallurgy. Coal reserves are six times greater than oil and petroleum
High quality coal (anthracite) is almost pure carbon. The combustion of carbon to carbon dioxide releases 393kJ per mol of carbon burnt. If 1kg of anthracite is burnt: a) How much heat is released?
In addition, bituminous coals that contain a fairly small amount of sulfur and cake (or “agglomerate”) easily are the only coals suited for making metallurgical coke—a hard, spongelike substance of almost pure carbon important for smelting iron ore. A major problem associated with the burning of bituminous coal is air pollution.
bituminous coals designate those that have the highest carbon content, and not too much ashes; the higher end of the bracket is called anthracite (almost pure carbon), sub-bituminous coals have a lower carbon content, with more ashes and water. They are younger than the bituminous coals,

Graphite forms from intense metamorphism and even igneous processing. • JET is the gem variety of coal. Generally derived from anthracite, jet is where the phrase "jet black
Coking Coal. Coking coal, a bituminous coal type also known as metallurgical coal or steel-making coal, is baked in a coke oven which forces out impurities to produce coke, which is almost pure carbon. This is considered one of the key irreplaceable inputs for the production of steel. Coke is a hard, porous, carbon-rich compound.
Coal is a rock formed from the decomposition of plant life. It is primarily composed of carbon, with many other trace elements.Coal's high energy density and extensive reserves found in nature make it useful as a fuel for electricity generation in coal-fired power plants, and in some places, heating..
