Arkansas coal has been used largely to produce steam to power electric generating plants and steam locomotives, as metallurgical coal in steel mills, to heat homes and buildings, and as a source of coal tar and other chemicals. The chemical and physical properties of a coal determine the use.
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Other important users of coal include alumina refineries, paper manufacturers, and the chemical and pharmaceutical industries. Several chemical products can be produced from the byproducts of coal. Refined coal tar is used in the manufacture of chemicals, .
Coal tar is used as the medication to heal itching, scaling, and flaking due skin conditions. It is also used in making medicated shampoo to treat dandruff and to kill lice. Soaps are made from coal tar. Various phenolic coal tars have the properties of a painkiller. Coal tar is used to protect and beautify the underlying pavement.

Coal is something that we might have come across at least once in our lifetime. It is a common substance used in many homes and even in big industries. That being said, we will be studying about coal and some of its uses here. Coal is basically a combustible sedimentary rock usually occurring in parts known as coal beds or coal seams.
Dec 12, 2011· The objective of proximate analysis indicates the percentage by weight of the Fixed Carbon, Volatiles, Ash, and Moisture Content in coal. The amounts of fixed carbon and volatile combustible matter directly contribute to the heating value of coal. Fixed carbon acts as a main heat generator during burning.

Modern coalquality data and geologic field observations are interpreted in terms of the coal geology in a small area near Pocahontas, Va. Detailed chemical analyses and physicalproperty determinations of 12 channelcoal samples (reported on wholecoal and laboratory ash basis) indicate that the coals are mostly of high coking quality, low
ENGINEERING PROPERTIES OF COMBINED COARSE AND FINE COAL WASTES by Bill M. Stewcrt l and L. A. Atkins2 ABSTRACT The Bureau of Mines conducted laboratory tests to determine the effects on the physical properties of coarse coal waste of adding large amounts of fine coal waste. Maximum laboratory dry density, optimum moisture content, shear

Coal Coal Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and .
The materials specifically covered by these standards can be in the form of lump coke, pulverized coal, bituminous coal, coke and coal ash, reformed gas, and polishing and etching coal. These standards also include the thermophysical property tables for methane, ethane, propane, normal butane, and isobutane.
Within 90 days, the Missouri plants were closed and turned back to the Department of the Army. The coal hydrogenation plant returned to making ammonia. For the remainder of the 1950s and into the 1960s, the Bureau of Mines coal and synthetic fuels research was relegated to lowpriority fundamental studies.
Jul 18, 2013· Coal, being a highly heterogeneous material, requires special care for determination of its properties and blending of individual coals for coke making. Coal fluidity is one such important coking property which highly influences the coke quality.

Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.. Anthracite is the most metamorphosed type of coal (but still represents lowgrade metamorphism), in which the carbon content is between 92% ...
Coal tar creosote is referred to as "creosote" by the EPA. The substance is a complex mixture typically composed of approximately 85% PAHs and 2–17% phenolics (Bedient et al. 1984). The composition of the mixture may also vary across lots and across manufacturers. Properties of coal tar creosote are shown in Table 46.
Visual analysis of logs for coal is relatively unambiguous. High neutron porosity, high density porosity (low density), high sonic, high resistivity, and clean gamma ray mean coal. Thresholds on each curve are used to trigger a coal flag. Three or more flags is a pretty good indication of the presence of coal.
