Hydrothermal dewatering of a Chinese lignite and ...

15-09-2016  Lignite can be efficiently upgraded by hydrothermal dewatering (HTD) process. • During HTD, organics and inorganics removed increase with HTD temperature. • After HTD, the hydrophobicity of coal is higher and increases with HTD temperature. • HTD coal has a higher spontaneous combustion tendency than the raw coal.

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.It has a carbon content around 25 to 35 percent. It is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation.
