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 ...

3. Coal Coal is a combustible,sedimentary, organic rock, formed from vegetation. In other words coal is a fossil fuel created from the remains of plants that lived millions of years ago. it is considered as a non renewable source of energy because it takes too much time to form. 4.
4. Coal Liquefaction Coal liquefaction is the conversion of coal into a synthetic oil in order to supplement natural sources of petroleum. It is an attractive technology because 1) It is well developed and thus could be implemented fairly rapidly and 2) There are relatively large quantities of coal reserves. 5.
Coal is a black sedimentary rock. It usually occurs in coal beds found in coal mines. Coal comprises of carbon, hydrogen, oxygen, sulphur, etc. When dead plants and animals decay and convert into peat which in turn is converted into lignite, then subbituminous coal, after that bituminous coal, and lastly anthracite. Hence, coal is a fossil fuel.
Bituminous coal is heavily utilized for energy in power plants and for the production of steel. Anthracite coal is known to be the cleanest burning coal but is one of the rarest, being found mainly in limited reserves in Pennsylvania. 6. How is coal used as a fossil fuel? Coal is usually extracted in mines.

Coal Formation • Unlike oil and natural gas, coal formed from decaying plants in ancient swamps. • When the peat is exposed to high temperatures and pressures, it forms coal. • There are three main types of coal: anthracite, bituminous, and lignite. Anthracite • It is the oldest and hardest form of coal.
Bituminous coal is the most abundant rank of coal found in the United States, and it accounted for about 45% of total coal production in 2021. Bituminous coal is used to generate electricity and is an important fuel and raw material for making coking coal or use in the iron and steel industry. Bituminous coal was produced in at least 16 ...
Coal Plant Matter, Carbonization, Sedimentary Rocks: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in lowlying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.
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.

Coal is a complex combination of materials, and the combination can greatly differ from one formation or deposit to another. These differences result from: 1. The varying types of vegetation from which the coal originated. 2. The depths of burial, and the temperatures and pressures at those depths. 3.
The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content. There are four ...
Presentation Transcript Nonrenewable fuels that formed long ago from the remains of plants and animals. Fossil Fuels: The origin of fossil fuels, starts with that if the reaction runs in reverse, it produces energy and releases carbon dioxide and water. Formation of Coal Coal is considered a Fossil Fuel.
ABSTRACT Coal is a solid, brittle, more or less distinctly stratified, combustible, carbonaceous rock. It is being rediscovered as a reliable energy source, which, historically provided the resource base for the industrialization of the United States' economy.
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.
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.
Examples of unconventional fossil fuels include oil shale, tight oil and gas, tar sands (oil sands), and coalbed methane. Figure 9: Conventional oil and natural gas deposits are trapped beneath impervious rock (gray). Conventional natural gas may be associated with oil or nonassociated. Coalbed methane and tight gas found in shale ...

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. Many of the source rocks for significant gas deposits appear to be associated with the worldwide occurrence of coal ...

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.
This process of separation of various constituents of petroleum is called petroleum refining. This is done in oil refineries. It is a threestep process. The first step is separation where the crude oil is separated into various components through the distillation process. The heavier constituents remain settled at the bottom whereas lighter ...

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.
