Coal, a combustible organic rock [1] composed primarily of carbon,
hydrogen, and oxygen [2]. Coal is burned to produce energy and is used
to manufacture steel. It is also an important source of chemicals used
to make medicine, fertilizers, pesticides [3], and other products.
Coal comes from ancient plants buried over millions of years in Earth’s
crust [4], its outermost layer [5]. Coal, petroleum, natural gas,
and oil shale [6] are all known as fossil fuels [7] because they
come from the remains of ancient life buried deep in the crust.

Coal is a sedimentary rock [1] formed from plants that flourished
millions of years ago when tropical swamps [2] covered large areas of
the world. Lush vegetation [3], such as early club mosses [4],
horsetails [5], and enormous ferns, thrived in these swamps.
Generations of this vegetation died and settled to the swamp bottom, and
over time the organic material lost oxygen and hydrogen, leaving the
material with a high percentage of carbon. Layers of mud and sand [6]
accumulated over the decomposed plant matter, compressing and hardening
the organic material as the sediments deepened. Over millions of years,
deepening sediment layers, known as overburden, exerted tremendous heat
and pressure on the underlying plant matter, which eventually became

Coal is rich in hydrocarbons [8](compounds made up of the elements
hydrogen and carbon). All life forms contain hydrocarbons, and in
general, material that contains hydrocarbons is called organic material.
Coal originally formed from ancient plants that died, decomposed, and
were buried under layers of sediment [9] during the Carboniferous
Period [10], about 360 million to 290 million years ago. As more and
more layers of sediment formed over this decomposed plant material, the
overburden [11] exerted increasing heat and weight on the organic
matter. Over millions of years, these physical conditions caused coal to
form from the carbon, hydrogen, oxygen, nitrogen, sulfur, and inorganic
mineral [12] compounds in the plant matter. The coal formed in layers
known as seams.

Before decayed plant material [7] forms coal, the plant material forms
a dark brown, compact organic material known as peat [8]. Although
peat will burn when dried, it has a low carbon and high moisture content
relative to coal. Most of coal’s heating value comes from carbon,
whereas inorganic materials, such as moisture and minerals [9],
detract from its heating value. For this reason, peat is a less
efficient fuel source than coal. Over time, as layers of sediment
accumulate over the peat, this organic material forms lignite [10],
the lowest grade of coal. As the thickening geologic overburden
gradually drives moisture from the coal and increases its fixed carbon
content, coal evolves from lignite into successively higher-graded
coals: subbituminous coal [11], bituminous coal [12], and anthracite
[13]. Anthracite, the highest rank of coal, has nearly twice the
heating value of lignite.

Plant matter changes into coal in stages. In each successive stage,
higher pressure and heat from the accumulating overburden increase the
carbon content of the plant matter and drive out more of its moisture
content [13]. Scientists classify coal according to its fixed carbon
content [14], or the amount of carbon the coal produces when heated
under controlled conditions. Higher grades of coal have a higher fixed
carbon content.

太阳娱乐,Coal formation began during the Carboniferous Period (known as the first
coal age), which spanned 360 million to 290 million years ago. Coal
formation continued throughout the Permian [14], Triassic [15],
Jurassic [16], Cretaceous [17], and Tertiary [18] Periods, which
spanned 290 million to 1.6 million years ago. Coals formed during the
first coal age are older, so they are generally located deeper in
Earth’s crust. The greater heat and pressures at these depths produce
higher-grade coals such as anthracite and bituminous coals. Conversely,
coals formed during the second coal age under less intense heat and
pressure are generally located at shallower depths. Consequently, these
coals tend to be lower-grade subbituminous and lignite coals.

Coal contains organic (carbon-containing) compounds transformed from
ancient plant material. The original plant material was composed of
cellulose [19], the reinforcing material [20] in plant cell walls
[21]; lignin [22], the substance that cements plant cells together;
tannins [23], a class of compounds in leaves and stems; and other
organic compounds, such as fats and waxes. In addition to carbon, these
organic compounds contain hydrogen, oxygen, nitrogen, and sulfur. After
a plant dies and begins to decay on a swamp bottom, hydrogen and oxyge

Coal also contains inorganic components, known as ash. Ash includes
minerals such as pyrite [24] and marcasite [25] formed from metals
that accumulated in the living tissues of the ancient plants. Quartz
[26], clay, and other minerals are also added to coal deposits by wind
and groundwater [27]. Ash [28] lowers the fixed carbon content of
coal, decreasing its heating value.
