Coal is a combustible black or brownishblack sedimentary rock composed mostly of carbon and hydrocarbons. It is the most abundant fossil fuel produced in the United States. Coal is a nonrenewable energy source because it takes millions of years to create. The energy in coal comes from the energy stored by plants that lived hundreds of millions of
Chemistry Coal and Petroleum Formation Of Fossil Fuels Formation of Coal How is Coal Formed? Coal is fossil fuel or fuel that comes from the remains of prehistoric plants or animals. The formation of coal occurs over millions of years via a process known as carbonation.
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 carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...
The formation of coal takes a long long time. The first coalbearing rock is said to have appeared about 350 million years ago. This period was known as the carboniferous period or the "coalbearing" period. Also, there are extensive coal deposits from the Cretaceous age i,e about 144 million years.
Petroleum is one of the most important and widely used fuels in today's time. Some of its advantages are: These are transportation fuels,, via air, water or land. Diesel is used to power turbines for the production of electricity in large scale industries. Oil is used to produce electricity at homes and shops.

Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
Other articles where coalification is discussed: coal: Peat: The process of peat formation—biochemical coalification—is most active in the upper few metres of a peat deposit. Fungi are not found below about metre (about 18 inches), and most forms of microbial life are eliminated at depths below about 10 metres (about 30 feet). If either the rate of.
Description: Coalification is a geological process of formation of materials with increasing content of the element carbon from organic materials that occurs in a first, biological stage into peats, followed by a gradual transformation into coal by action of moderate temperature (about 500 K) and high pressure in a geochemical stage.

In this way, first lignite (also called 'brown coal'), then subbituminous coal, bituminous coal, and lastly anthracite (also called 'hard' or 'black' coal) may be formed. The wide, shallow seas of the Carboniferous Period provided ideal conditions for coal formation, although coal was formed in most geological periods.

18. CLASSIFICATION It classifies coal to 4 broad classes based on fixed carbon and calorific value (BTU) on dry mineral matter free basis. Applicable only to vitrinite rich coal and excludes southern Gondwanaland coal Gross Heating Value found on a moist and mineral matter free basis.
Most coal has some methane (the main component of natural gas) trapped inside it. This methane is produced during the coal formation process and gets trapped on the surface of the coal in tiny pores and fractures. 1 Many coalbeds also contain large amounts of water; the pressure from this water keeps the methane in place. Coalbed methane is extracted by pumping out the water, which lowers the ...

What Is Coal Preparation? • Coal preparation is the removal of undesirable material (ash, Sulphur, moisture)from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities.
Theories of Coal Formation. The natural agencies causing the observed chemical and physical changes include the action of bacteria and fungi, oxidation, reduction, hydrolysis and condensation the effect of heat and pressure in the presence of water. Many factors determine the composition of coal. Mode of accumulation and burial of the plant ...
12. PEAT • Peat is also known as turf. • First stage of transformation. • Contains less than 40 to 50 % Carbon. • Contains sufficient volatile matter and lot of moisture. 13. LIGNITE • Lower grade coal. • Moisture content is High. • 40 to 55 % carbon content. • Contains brown to black woody substances.
Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal.

COAL : DEFINITION Coal is a stored fossil fuel, occurring in layers in the earth's crust, which has been formed by the partial decay of plant materials accumulated millions of years ago and further altered by the action of heat and pressure. 4. COAL FORMATION. 5.
Origin of natural gas Organic formation process. Natural gas is more ubiquitous than oil. It is derived from both land plants and aquatic organic matter and is generated above, throughout, and below the oil, all source rocks have the potential for gas generation.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, 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.
There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]
