BITUMINOUS Meaning and
Definition
-
Bituminous is an adjective used to describe a type of coal or rock that contains a significant amount of bitumen, a mixture of hydrocarbons found in petroleum. The term also refers to substances that have bitumen as a major component or characteristic, or that are directly related to or derived from bitumen.
In relation to coal, bituminous refers to a medium-rank coal that is commonly used for power generation and industrial purposes. It is characterized by its relatively high carbon content, which ranges from 45 to 86 percent, and its moderate energy-producing properties. Bituminous coal is formed through the progressive alteration of lignite or sub-bituminous coal, resulting in a material with a greater carbon concentration and more energy content. It is typically black or blackish-brown in color and has a relatively high moisture content.
Outside the realm of coal, the term bituminous can refer to a variety of substances, such as asphalt, tar, or certain types of natural deposits. Asphalt commonly used in road construction and roofing materials is a bituminous substance, as it contains bitumen as a binding agent. Similarly, tar, which is a dark and viscous liquid derived from coal or wood, is considered bituminous. Natural bituminous deposits, often referred to as asphalt deposits or tar pits, are geological formations where bitumen has accumulated over long periods of time. These deposits are found in various parts of the world and are sometimes used as a source of valuable hydrocarbons.
