  • Sulphur And Coal Global Energy Monitor

    All coal contains sulphur, though the amount varies significantly. The U.S. coal company, Foundation Coal, stated in its 2008 annual report that sulfur content can vary from seam to seam and sometimes within each seam. When coal is burned, it produces sulfur dioxide, the amount of which varies depending on the chemical composition and the concentration of

  • Sulfur In Coals A Review Of Geochemistry And Origins

    For low-sulfur coal ( 1% S), sulfur is derived primarily from parent plant material. For medium-sulfur (1 to 3% S) and high-sulfur ( 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
