Coal Liquefaction Process

Coal Liquefaction an overview ScienceDirect Topics

Coal liquefaction is the process of making a liquid fuel from coal. The fundamental difference between coal, a solid, and liquid fuels is that the liquid fuels have a higher hydrogen:carbon ratio. Liquid fuels have lower ash contents and are easier to upgrade (i.e., to remove unwanted impurities such as
