    Lignite - Wikipedia

    Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. Lignite has a high content of volatile matter which makes it easier to convert into gas and liquid petroleum products
