Peat depositional environments, the sites where and conditions under which peat
accumulates, significantly influence a resultant coal's physical properties, chemical …

Geochemical studies of sulfur in coals comprise several major aspects relating to the nature
and origin of sulfur in coals, including the abundance and distribution of sulfur in coal …

We present multi-element data on the super-high-organic-sulfur (SHOS; 5.19% on average)
coals of Late Permian age from Guiding, in Guizhou Province, China. The coals, formed on …

Fly ash (FA) is a major industrial waste generated from power stations that add extra cost for
proper disposal. Recent research efforts have consequently focused on developing ways to …

Activated carbon (AC) is made from waste oil fly ash (OFA) which is produced in large
quantities from power generation plants through combustion of heavy fuel oil. OFA …

Coal-fired power plants (CFPPs) are the dominant source of electricity in South Africa due to
coal abundance in the country. However, emissions of SO2, Pb, and Hg have raised serious …

The superhigh-organic-sulfur (SHOS) coals of the Late Permian from the Chenxi coalfield,
Hunan Province, China are deposited in a carbonate tidal flat and have an organic sulfur …

The geochemical characteristics of sulfur and nitrogen contents and isotopic compositions in
a special coal, the Late Permian bark coal of southern China, were investigated by …

In this study, surface modification of oil fly ash (OFA), a by-product generated by oil power
plants, was achieved by chemical treatment. A mixture of sulfuric and nitric acids was used …

The geochemical study of sulfur in coal can not only reveal the source and occurrence of
sulfur in coal and provide information about the depositional environment and coal formation …
