"Bitumen" redirects here. For naturally occurring bituminous sands used for petroleum production

The terms bitumen and asphalt are mostly interchangeable, except where asphalt is used as an abbreviation for asphalt concrete

The primary use of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.

The terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Natural deposits terminology also sometimes uses the word bitumen,

The substance is completely soluble in carbon disulfide, and composed primarily of a mixture of highly condensed polycyclic aromatic hydrocarbons; it is most commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase (though there is some disagreement amongst chemists regarding its structure). One writer stated although a "considerable amount of work has been done on the composition of asphalt, it is exceedingly difficult to separate individual hydrocarbon in pure form",[8] and "it is almost impossible to separate and identify all the different molecules of asphalt, because the number of molecules with different chemical structure is extremely large".[9]

Most natural bitumens contain sulfur and several heavy metals, such as nickel, vanadium, lead, chromium, Mercury, arsenic, selenium, and other toxic elements.[citation needed] Bitumens can provide good preservation of plants and animal fossils.

What is bituminous coal?

Bituminous coal is a type of coal that is commonly used for energy production and heating. It has a higher carbon content than lignite and sub-bituminous coal, making it a more efficient fuel source. Bituminous coal is known for its relatively high heat content and is often used in industrial processes and electricity generation.


What type of coal does Montana mine?

Montana mainly mines sub-bituminous coal. This type of coal has a lower energy content and higher moisture content compared to bituminous coal, making it less desirable for some applications.


What are the differences between the types of coal?

The main types of coal are anthracite, bituminous, and lignite. Anthracite is the highest rank of coal and has high carbon content, making it the cleanest burning coal. Bituminous coal has a lower carbon content and is commonly used for electricity generation. Lignite is the lowest rank of coal, with the highest moisture content and lowest carbon content, making it less energy-dense than anthracite and bituminous coal.


What are the varieties of coal formed inside the earth?

wood-peat-lignite-subbituminous-bituminous-anthracite The wood is converted to anthracite (coal) through various stages. lignite, subbituminous,bituminous,anthracite are the major coal types formed these are ranked based on the presence of carbon ,hydrogen and oxygen content


What is the difference between lignite and bituminous coal?

Lignite is a low-grade coal with low carbon content and high moisture content, making it less energy-dense than bituminous coal. Bituminous coal, on the other hand, has a higher carbon content and energy density, making it a more valuable and widely-used form of coal for energy production.


Which coal type is harder anthracite or bituminous?

Anthracite is harder than bituminous coal. Anthracite has a higher carbon content and lower moisture content, making it a more dense and harder coal type.

What are the 4 types of Cole?

The four types of coal are anthracite, bituminous, sub-bituminous, and lignite. Anthracite is the highest grade, characterized by its hard, glossy appearance and high carbon content, making it an efficient fuel. Bituminous coal is the most commonly used type, primarily for electricity generation and steel production. Sub-bituminous coal has lower carbon content and energy output, while lignite, or brown coal, is the lowest grade, with high moisture content and limited energy capacity.


What is the difference in peat bituminous lignite and anthracite?

Peat is an organic matter with the lowest carbon content and a precursor to coal. Bituminous coal has a higher carbon content than peat and is widely used for electricity generation. Lignite is a low-grade coal with a higher carbon content than peat but lower than bituminous coal. Anthracite is the highest grade of coal with the highest carbon content and the cleanest-burning properties.


What does bituminous coal?

Bituminous coal is a type of coal known for its high carbon content and energy value. It is widely used in electricity generation, steel production, and industrial processes due to its relatively high heat content compared to other types of coal. Bituminous coal is formed when heat and pressure are applied to organic matter over millions of years.


What are the four forms of coal?

The four forms of coal are lignite, sub-bituminous, bituminous, and anthracite. These forms differ in their carbon content and energy value, with lignite being the lowest in carbon content and anthracite being the highest.
