Coal liquefaction - Energy Education

2021-8-5  Coal liquefaction. Coal liquefaction is a process in which coal is converted into liquid fuels or petrochemicals. There are several processes used to accomplish this task, the two most common being the "indirect route" and the "direct route". The indirect route is composed of 2 steps: First, coal is gasified with steam and oxygen to produce a ...
