What Are the Four Stages in Coal Formation?

Mar 30, 2020· Stage two of the coal formation process is lignite. Lignite forms when peat is put under considerable vertical pressure. It contains small amounts of plant matter and is very fragile so it must never be handled before burning. Bituminous coal is the third stage of coal production. The lignite continues receiving heavy vertical pressure until it

Coal liquefaction Wikipedia

Indirect coal liquefaction (ICL) processes operate in two stages. In the first stage, coal is converted into syngas (a purified mixture of CO and H 2 gas). In the second stage, the syngas is converted into light hydrocarbons using one of three main processes: Fischer–Tropsch synthesis, methanol synthesis with subsequent conversion to gasoline or petrochemicals, and methanation.
