Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.
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.

A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis. Such organisms and their resulting fossil fuels typically have an age of millions of years, and sometimes more than 650 million years. Fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.

Aug 27, 2012· This coal has a carbon content of around 25-35%. The carbon content is an indicator or its purity for fuel. Having a high moisture content of brown coal, carbon dioxide emissions from brown coal fired plants are generally much higher than for comparable black coal plants. This is clearly not a home heating type of coal. Assam Coal. Reply Delete
Jan 29, 2020· Coking vs. Steam: Coking coal, also known as metallurgical coal, has low sulfur and phosphorus content and can withstand high heat.Coking coal is fed into ovens and subjected to oxygen-free pyrolysis, a process that heats the coal to approximately 1,100 degrees Celsius, melting it and driving off any volatile compounds and impurities to leave pure carbon.
There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon rich, and harder material. The four ranks are:
Metallurgical 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. It is important for metallurgical coal to have low sulphur and phosphorous contents.
Anthracite is the highest rank of coal. Unlike other types of coal, it is usually considered to be a metamorphic rock. It has a carbon content of over 87% on a dry ash-free basis. Anthracite coal generally has the highest heating value per ton on a mineral-matter-free basis.
Coal definition of Coal in the Free Online Encyclopedia.. Anthracite, which is nearly pure carbon, is very hard, black, and lustrous and is The natural, rocklike, brown to black derivative of forest-type plant material, usually Coal is increasingly used to obtain high-carbon coal-graphite construction
Classifications of Coal. There are four basic types of coal. Classifications, or coal ranks, are based on how much carbon, volatile matter, and heating value are contained in the coal: Anthracite (hard coal) is the highest-ranked coal. It is hard and jet-black, with a moisture content of less than 15%.
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.
Chapter 7 COAL If we as a nation are to benefit in the future from our enormous, low-cost coal reserves, a Coal type Approximate age (years) Approximate carbon content, % ultimate analysis of coal. Carbon and hydrogen are the principal combustible elements in coal. On a weight basis, carbon is the predominant one.
Coke is made by putting a certain blend of coal into an oven and baking it. Making coke is like making charcoal from wood. It is the process of pyrolysis or gasification. Coal is turned into coke by driving off the hydrocarbons in the oven leaving...

Sep 17, 2012· India is poised to contend with China as the globe's top consumer of coal, with 455 power plants preparing to come online, a prominent environmental research group has concluded.
Carbon. Pure, elemental carbon is found widely dispersed in nature, and can show 3-5 allotropic forms, depending on how you count them.. Graphite. is one of the softest substances known, and is used in a variety of ways. It is the "lead" in a pencil and a lubricant in locks or where metal rubs against metal.
