Subbituminous coal can be formed at a very low temperature of 35℃ to 80℃ while anthracite is formed under a very high temperature of at least 180℃ to 245℃. Also, favourable geology does not only contribute to the formation of coal but other factors like the presence of oxygen also contribute to the high coal deposition.

The arc process, however, was costly and inherently inefficient in its use of energy, and it was soon abandoned for better processes. One such method used the reaction of nitrogen with calcium carbide at high temperatures to form calcium cyanamide, which hydrolyzes to ammonia and cyanamide process was utilized on a large scale by several countries before and during World War I, but it ...

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

A diagram is given illustrating the extent of change in the plant material, in comparison with diagenetic and metamorphic intensity. Since coal beds generally include various proportions of the diverse materials resulting from the three processes, practical classification of coal is intimately related to the part each process has played.

Petroleum is a mixture of many substances such as gas, petrol, diesel, kerosene, lubricating oil, paraffin wax, etc. As these constituents serve different purposes, it is important to separate them, or in other words, refine the crude oil. This process of separation of various constituents of petroleum is called petroleum refining.

Overlaying of sediments over the burial results in the formation of fossil fuels due to exposure to high pressure for a very long period of time. The 3 main types of Fossil Fuels are Coal, Oil Natural Gas. Natural coal is formed due to the burial of plants and animals. Petroleum and natural gas are a result of the buried marine life.

It is the coal with the lowest carbon content. The carbon content is only about 6070 %. It is formed during the younger stages of coal formation and thus has a lower carbon content. Due to the less amount of carbon, it is not fully black in colour and is somewhat brown. Lignite is used in electricity generation and in fertilizer production.

Coal formed millions of years ago when the earth was covered with huge swampy forests where plants giant ferns, reeds and mosses grew. As the plants grew, some died and fell into the swamp waters. New plants grew up to take their places and when these died still more grew. In time, there was thick layer of dead plants rotting in the swamp.

Water gas is a kind of fuel gas, a mixture of carbon monoxide and is produced by "alternately hot blowing a fuel layer [coke] with air and gasifying it with steam". The caloric yield of this is about 10% of a modern syngas plant. Further making this technology unattractive, its precursor coke is expensive, whereas syngas uses cheaper precursor, mainly methane from natural gas.

The formation of coal is a fourstage process, depending on the conditions to which the plant debris was subjected. More the heat and pressure to which vegetation is subjected, better is the quality of coal. Superior quality coal is denser, has more carbon content, contains lesser moisture and has a better calorific value. ...

Uses of Coal. It is mainly used to generate heat and electricity. It is used in s and in industries to accomplish various tasks. It is the cheapest source of power fuel. The iron and steel industry depends heavily on fossil fuel for energy. It is also used to produce useful products such as coke, tar, and coal gas.

Answer. Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial ...

Solution. Verified by Toppr. The process of fusion of male gamete with the gamete to form the diploid zygote (2n) is known as fertilisation. The fusion of one male gamete with egg and that of another male gamete with a secondary nucleus is called double fertilisation. It is the characteristic feature of only angiosperms.

Coal is extracted from mines. The wood is converted first into a spongy material called peat, then lignite, and eventually into coal (anthracite) and following these steps coal is formed. Carbonization: The slow process of conversion of wood into coal over millions of years is called carbonization.

sedimentary rock, rock formed at or near Earth's surface by the accumulation and lithification of sediment (detrital rock) or by the precipitation from solution at normal surface temperatures (chemical rock). Sedimentary rocks are the most common rocks exposed on Earth's surface but are only a minor constituent of the entire crust, which is dominated by igneous and metamorphic rocks.

The process of coal formation is called carbonisation. The dead plants and vegetation due to temperature and high pressure over hundreds of years slowly turned into coal. This slow conversion of dead plants and forests into coal is called the process of carbonisation. The process is called so because coal largely contains carbon.
