Conversion of coal to diamonds is a natural process that takes millions of years. Even though there are carbon atoms in coal, the amount of impurities are so high, that it takes millions and millions of years for the coal to transform to its nearly purest form – graphite. The conversion of graphite to diamonds takes some more millions of years.

Pyrolysis: A sustainable way from Waste to Energy

Biomass can be converted into heat and electricity in a number of ways. Depending on its source, these processes include: combustion, pyrolysis, gasification, liquefaction, anaerobic digestion or fermentation. Thermo-chemical processes convert biomass into higher-value or more convenient products. The process releases a gas (~6 MJ/kg), a liquid

Moisture Correction for Coal Analysis

The heating value of coal depends on the Combustible Matter, mainly Carbon and Hydrogen, in the coal and how it reacts during the combustion process. Apart from the Combustible Matter the other main ingredients are Ash and Moisture. In its journey from the mines to the power plant, Combustibles and the Ash in the Coal remain unchanged.

What are the different types of coal?

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.

International Journal of ChemTech Research

difference can be explained by differences in the heating value of Indian coal: the heating value of Indian coal is, on average, about 60 percent of the heating value of coal burned in the United States [9]. The problems are exacerbated because of the multiplicity of supply sources. There are very few power plants (except some pit head

Rocks and Minerals

Our Earth is made mostly of rocks. The rocks are composed of mineral grains combined in different ways and having various properties. Minerals are naturally occurring chemical compounds in which atoms are arranged in three-dimensional patterns. The kind of elements and their arrangements lead to a particular appearance and certain properties for each mineral.

THE COAL RESOURCE

Coal is one of the world's most important sources of energy, fuelling almost 40% of USA, Russia, China and India. Resource The amount of coal that may be present in a deposit or coalfield. This does not take into differences even within a single mine can lead. World Coal Institute. World Coal Institute.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

That loss produces coal with a higher carbon content (71 to 77% on a dry ash-free basis). Sub bituminous coal has a heating value between 8300 and 13000 British Thermal Units per pound on a mineral-matter-free basis. On the basis of heating value, it is subdivided into sub bituminous A, sub bituminous B, and sub bituminous C ranks.

Coke (fuel)

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term coke usually refers to the product derived from low

Uses of coal

Different types of coal have different uses. Steam coal - also known as thermal coal - is mainly used in power generation. Coking coal - also known as metallurgical coal - is mainly used in steel production. Other important users of coal include alumina refineries, paper manufacturers, and the chemical and pharmaceutical industries.

Where is coal found?

After centuries of mineral exploration, the location, size and characteristics of most countries' coal resources are quite well known. What tends to vary much more than the assessed level of the resource - i.e. the potentially accessible coal in the ground - is the level classified as proved recoverable reserves.

* Energy contents are expressed as either High (gross) Heating Value (HHV) or Lower (net) Heating Value (LHV). LHV is closest to the actual energy yield in most cases. HHV (including condensation of combustion products) is greater by between 5% (in the case of coal) and 10% (for natural gas), depending mainly on the hydrogen content of the fuel.
