The described systems and methods are versatile and may be used to generate a variety of high value products including chemicals (aromatics, asphaltenes, napthenes, phenols, polyamides, polyurethanes, polyesters), polymer ...

The Types of Coal: Composition, Usage, and Energy Value ThoughtCo

Steam coal, also known as thermal coal, is suitable for electric power production. Steam coal is ground into a fine powder that burns quickly at high heat and is used in power plants to heat water in boilers that run steam turbines. It also may be used to provide space heating for homes and businesses.

In time, material that had been plants became coal. Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite. These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal. Coal is defined as a readily combustible rock containing more than 50% by weight of carbon.

The ash stored underground can slowly leach into groundwater, and the wet slurry can break through a pond's earthen walls, as it did at a coal ash storage pond near Knoxville, Tennessee in 2008. We can convert solid coal into synthetic natural gas by a process called coal gasification, which removes sulfur and most other impurities from coal.
