  • 10.6. Direct Liquefaction Processes | netl.doe.gov

    Reason for Discussion of Direct Liquefaction of Coal in Gasifipedia As the following discussion of Direct Coal Liquefaction (DCL) explains, the fundamental process approach of DCL does not involve gasification at all. Therefore it would seem to be entirely out of scope of Gasifipedia. However, the following considerations require that discussion of DCL be included:

  • Formation of coal – Electric Universe Geology

    According to the current state of knowledge, coal is produced in nature by the so-called "carbonization" of plant parts. The biological material is initially transformed into peat in the absence of air by squeezing of pore water and biochemical processes and with further progression transformed by a diagenetic process gradually into lignite.

  • How Coal Works | Union of Concerned Scientists

    Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.
