Coal Composition an overview ScienceDirect Topics

The moisture content of peat varies from 75% to 90% and it is assumed that the water is a remnant from the depositional environment. Coalification reduces the moisture content of peat to about 30–40% in lignite, about 20–25% in subbituminous coal, and about 1–10% in bituminous coal; the latter decreasing from high to low volatile rank.

Coal explained U.S. Energy Information Administration (EIA)

Lignite contains 25%–35% carbon and has the lowest energy content of all coal ranks. Lignite coal deposits tend to be relatively young and were not subjected to extreme heat or pressure. Lignite is crumbly and has high moisture content, which contributes to its low heating value. Lignite accounted for 9% of total U.S. coal production in 2020.
