Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat.It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content.Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation.

The aim of this research was to investigate DCL process by the co-processing of brown coal with model-, petroleum- and waste-derived solvents. The brown coal with and without W, Fe and Mo metals supported on its surface was tested. Thirteen DCL tests with added hydrogen pressure were carried out in the autoclave.

Prone to spontaneous combustion, brown coal is hardly ever used. On the other hand, because brown coal is noted for its low ash and sulfur, it has the advantage of being environment-friendly when burned. By removing the moisture, Kobe Steel''s UBC Process raises the heat value, thereby converting brown coal into a high-grade energy resource.
