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 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.

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.

Coal beds consist of altered plant remains. When forested swamps died, they sank below the water and began the process of coal formation. However, more than a heavy growth of vegetation is needed for the formation of coal. The debris must be buried, compressed and protected from erosion. Even though all the biological, geographic and

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...

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.

All coals, regardless of whether they are caking or coking coals, leave a solid carbonaceous residue at the end of the carbonization process. Chars, if heattreated to extreme temperatures, ≥2500 °C, do not form graphite, while cokes do. That is, chars are nongraphitizable, while cokes are graphitizable [A]. Type.
