Bituminous coal composition

Bituminous coal contains moisture of up to approximately 17%. About 0.5 to 2 percent of the weight of bituminous coal is nitrogen. Its fixed carbon content ranges up to approximately 85 percent, with ash content up to 12% by weight The glassy material in most bituminous coal is vitrinite, composed of macerals derived primarily from woody plant tissue. Because of its relatively high heat value and low (less than 3 percent) moisture content, its ease of transportation and storage, and its abundance, bituminous coal has the broadest range of commercial uses among the coals

It can be seen that CH 4 (the most abundant), CO 2, H 2, CO, and C 2 H 6 are the major components of pyrolysis gas (The composition of a bituminous coal by percentage is roughly: carbon [C], 75-90; hydrogen [H], 4.5-5.5; nitrogen [N], 1-1.5; sulfur [S], 1-2; oxygen[O], 5-20; ash, 2-10; and moisture, 1-10. Abstract A procedure for the extraction, separation and characterization of coal bitumen is described. A Carboniferous coal was subjected to exhaustive (single-step) extraction with dimethylacetamide (DMAA) at ambient temperature. The treatment solubilized ∼24 wt% of the organic matter. The bitumen was fractionated further and some fractions were separated into normal and branched/cyclic. Physical and chemical analyses of 12 coal-channel samples from McDowell County, W. Va., and Tazewell County, Va., indicate that 11 samples are of metallurgical quality. The 11 samples consist of medium-volatile bituminous coal that is low in sulfur and ash and of good coking quality

Bituminous coal coal classification Britannic

Bituminous coal has a composition of about 84.4% carbon, 5.4% hydrogen, 6.7% oxygen, 1.7% nitrogen, and 1.8% sulfur, on a weight basis. This implies that chemical processes during coalification must remove most of the oxygen and much of the hydrogen, leaving carbon, a process called carbonization Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite. These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal. Coals other constituents include hydrogen, oxygen, nitrogen, ash, and sulfur. Some of the undesirable chemical constituents include chlorine and sodium

Coal composition is important in determining the micropore capacity and size distribution and hence the gas capacity of bituminous coals. Copyright C~ 1996 Elsevier Science Ltd. (Keywords: coal; micropore structure; petrography) Large quantities of natural gas, mainly methane, are produced during the biochemical and geochemical stages of coalification Bituminous Coal: Bituminous coal is typically a banded sedimentary rock. In this photo you can see bright and dull bands of coal material oriented horizontally across the specimen. The bright bands are well-preserved woody material, such as branches or stems Bituminous Coal:Great pressure results in the creation of bituminous, or soft coal. This is the type most commonly used for electric power generation in the U.S. It has a higher heating value than either lignite or sub-bituminous, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest & Appalachi Bituminous coals are by far the largest group and are characterized as having lower fixed carbon and higher volatile matter than anthracite. The key distinguishing characteristics of bituminous coal are its relative volatile matter and sulfur content as well as its slagging and agglomerating characteristics

from coal combustion are primarily sulfur dioxide (SO 2), with a much lower quantity of sulfur trioxide (SO 3) and gaseous sulfates. These compounds form as the organic and pyritic sulfur in the coal are oxidized during the combustion process. On average, about 95 percent of the sulfur present in bituminous coal will be emitted as gaseous SO In this study, the characterization of bituminous coal, sub-bituminous coal and bottom ash from a coal fired power plant was performed. Moisture content, loss of ignition and heat of combustion. bituminous coal composition. December 16, 2020 /Parent 5 0 R Despite these extensive chemical changes, the physical structure of lignin is maintained through early-stage coalification, and intact cell structure of woody tissue is clearly visible in scanning electron micrographs

Sub-bituminous coal is considered black coal, even though its appearance varies from bright black to dull dark brown. Its consistency ranges from hard and strong to soft and brittle due to its intermediate stage—between bituminous and brown coal (lignite) Definition: A composition fuel made of brown coal produced by briquetting under high pressure with or without the addition of a binding agent. Remark: Either Sub‐bituminous Coal or Lignite may be used including dried lignite fines and dust

In bituminous coal ashes, these spherical particles are mostly made of SiO 2 and Al 2 O 3 with addition of sodium and potassium (Fig. 7 a). Sodium oxide and potassium oxide are especially present in particles of ash whose size is below 45 μm, which is probably due to their lower melting temperature and condensation on the smallest ash particles coal with lower degree of coalification (peat and lignite), in bituminous coal they are formed only by post-sedimen-tary oxidation. Petrographic composition is an important factor that influences total change of coal matter. Another factor is the degree of coalification characterized by parameters: Vdaf, R oand elementary composition (Klika and. Anthracite coal forms when bituminous coal undergoes very low grade metamorphism, accompanied by structural deformation. The fixed carbon content under these conditions reaches 85-95%. If anthracite is metamorphosed further it turns into graphite Coal tar itself is produced by the carbonization, or coking of coal. Coal tar is defined by Hawley (1977) as: A black, viscous liquid (or semi-solid), naphthalene-like odor, sharp burning taste; obtained by the destructive distillation of bituminous coal, as in coke ovens; 1 ton of coal yields 8.8 gallons of coal tar. Combustible

Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous coal usually has a high heating (Btu) value and is used in electricity generation and steel making in the United States. Coal is black or brownish-black, and has a composition that (including inherent moisture). of bituminous coal with pre-dried lignite in a pilot scale combustor, measured by a heated Electrical Low Pressure Impactor (ELPI+), and subsequent impact on flue gas-cleaning devices.

Coal composition. Coal is a mineral in which the chemical element of carbon is prevalent. Carbon content (the so-called coalification) depends foremost on the time during which the conversion from plant matter to the final mineral took place.The older the coal, the higher the carbon percentage and the less apparent the original vegetable component, i.e. the fossil, remains of plant tissues.

Sub-bituminous coal is a dull dark brown to black and not shiny type of coal. It has a higher heating value than lignite and it is mainly used as a fuel for steam-electric power plants. Sub-bituminous coal can be found in Montana, Colorado, Wyoming, New Mexico, Alaska, and Washington bituminous coal Bituminous coals and anthracites are often referred to as hard coal because of their physical structure, while lignite and brown coal are commonly referred to as soft coal The elemental composition of organic matter in coal continues to change during late-stage coalification ( Figure 7 )..
