Metallurgical Coal, Kentucky Geological Survey, University 19/09/2019 Coals from western Kentucky are typically not used for steel production (eg, met coal), because of their high sulfur content Several coal beds in eastern Kentucky meet the lowash and sulfur requirements of metallurgicalgrade coal feedstock, but unfortunately they typically have volatile matter contentsDescription of Coal The fuel burned in Unit A consisted of a highvolatile bituminous coal from Pennsylvania The coal for Unit B, representing two levels of sulfur content, was supplied from a Kentucky strip mine and a West ia deep mine (Table I) Summary of Tests Five tests on Unit A were intended to evaluate emissions at normal fullloadtypical high sulfur content kentucky coal ladolceitaliafr

Several coal beds in eastern Kentucky meet the lowash and sulfur requirements of metallurgicalgrade coal feedstock, but unfortunately they typically have volatile matter contents (in the mid to high 30’s) that are too high for use in steel production As such, most eastern Kentucky coals are not used by themselves to produce cokeTwo coals, one from western Kentucky and one from eastern Kentucky, both with highorganicsulfur content, were examined by scanning and TEM methods With the caveat that the minerals are fine and the volume examined by SEM–EDS may include multiple minerals, the western Kentucky coal had areas with Pb and Cd in addition to the expected Fe and SUltrafine Mineral Associations in SuperhighOrganicSulfur
Sulfur in coals: A review of geochemistry and origins
For mediumsulfur (1 to < 3% S) and highsulfur (≥ 3% S) coals, there are two major sources of sulfur: 1) parent plant material, and 2) sulfate in seawater that flooded peat swamps Abundances of sulfur in coal are largely controlled by the degree of seawater influence during peat accumulation and by postdepositional changes (diagenesis)The sulfur content in coals varies considerably but is most commonly within the range of 05% to 5% total sulfur The coal with less than 1% sulfur is classified as lowsulfur coal Coal with 1% to < 3% sulfur is mediumsulfur coal Coal with ≥ 3% sulfur is highsulfur coalSulfur in coals: A review of geochemistry and origins
