    Subbituminous Coal Characteristics Thoughtco

    Mar 15, 2019 Sub-bituminous coal is noncoking and contains less sulfur but more moisture (approximately 10 to 45 percent) and volatile matter (up to 45 percent) than other bituminous coal types. It has 35 to 45 percent carbon content, and its ash content ranges up to 10 percent. The coal's sulfur content is generally less than 2 percent by weight.

  • Coal Wikipedia

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.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.
