Coal in a Nutshell - ThoughtCo

23-01-2020· Coal comes in three main types or grades. First, the swampy peat is squeezed and heated to form brown, soft coal called lignite. In the process, the material releases hydrocarbons, which migrate away and eventually become petroleum. With more heat and pressure lignite releases more hydrocarbons and becomes the higher-grade bituminous coal.

Lignite - an overview | ScienceDirect Topics

Lignite, or brown coal, is the lowest-ranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which average 8500–14 000 Btu/lb).

What is coal? | World Coal Association

In comparison to other coals, lignite is quite soft and its colour can range from dark black to various shades of brown. Over many more millions of years, the continuing effects of temperature and pressure produces further change in the lignite, progressively increasing its organic maturity and transforming it into the range known as 'sub-bituminous' coals.
