Indiana Center for Coal Technology Research 12 SULFUR IN COAL Although coal is primarily a mixture of carbon (black) & hydrogen (red) atoms, sulfur atoms (yellow) are also trapped in coal, primarily in two forms. In one form, (1) the sulfur is a separate particle often linked with iron (green, pyritic sulfur) with no connection to the carbon. of its high content of ash and sulfur, and its low heat the reserve base of sub-bituminous coal in the the average efficiency of electricity generation from coal in the U.S. to plummet to.
The U.S. Energy Information Administration (EIA) reported that U.S. coal production in increased % to mil-lion short tons, a new U.S. record (table 1). This upturn result-ed from 16 of the 26 coal producing states having increased production in , including production increases at the top five producing states. In addition, the sulfur, heat, and ash content of the Danville and Springfield Coals were mapped in order to allocate indicated reserves, demonstrated reserve base, accessible reserve base, and.
The use and production of coal is on the decline, pressured by cheap natural gas and policies to promote cleaner sources of energy. In a recent article in The Regional Economist, Regional Economist Charles Gascon and Senior Research Associate Jonas Crews took a deeper look at the future of coal production as a source for both electricity and jobs in the U.S. According to the Department of Energy, the U.S. has a billion-metric-ton demonstrated coal reserve current technologies, consumption of the U.S. coal reserve base.

The parameters used to establish the reserve base definition are the result of a joint agreement by the federal Bureau of Mines and the U.S. Geological Survey. The reserve base of low-sulfur coal, / = percent sulfur, ismillion tons; medium-sulfur coal, to percent sulfur, is 37, million tons; and high-sulfur coal, > 3.

The sulfur content of United States coal can be assessed using a variety of approaches. The sulfur content may be expressed in terms of total sulfur in the coal, pounds of sulfur per million Btu, or sulfur remaining after reduction by coal preparation. In addition, sulfur content may be applied to the demonstrated reserve base or to coal resource estimates.
Preferred coking coals from the bituminous grades are low in volatile matter and moisture content, high in fixed carbon, and low in such impurities as ash, sulfur, alkali, and phosphorus. Because no single coking coal has all the properties blast-furnace operators prefer, blends of coking coals from multiple sources are most commonly used.
sulfur coal reserves tend to occur in some areas of the eastern United States (east ern Kentucky and southern West Virginia), but mainly in the western United States.
The sulfur content of most U.S. coals ranges between 1% and 3%, giving an average of approximately % by weight. Coal Ownership Coal ownership is an important aspect of the. further as electric utilities switch from high-sulfur Illinois Basin coal to low-sulfur western coal.

ABSTRACT Conventionally,thedefinitionoflowsulfurcoal,onwhichtradi-tionalreserveandsupplyestimatesarebased,dependsonlyontheweight ofsulfurinatonofcoal. Conventionally, the definition of low sulfur coal, on which traditional reserve and supply estimates are based, depends only on the weight of sulfur in a ton of coal.
The Btu content of coal is not considered. However, coal purchases and SO 2 regulations are based on Btu content. A recalculation of reserve estimates of low sulfur coal on a. The cumulative results from the four PRB assessment areas are BST of coal reserves and a total recoverable coal resource (coal reserve base) of BST in coal beds greater than 5 ft in thickness and less than a stripping ratio.
So far 11 billion tons of coal filling 95 million rail cars have been removed.

Under proposed guidelines, even low sulfur, western bituminous coals require some cleaning to meet new source standards of lb. of SO2 per million Btu's ( kg SO2/1 GJ) and 90% reduction in sulfur content of the coal. Typically, Illinois Basin coals contain more sulfur than coals from other coal bearing regions.The ERR is categorized by state, Btu (British thermal unit) value, sulfur content, and mining type—it is the most widely reported and frequently quoted estimate of U.S.
