Coal liquefaction - Energy Education

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 ...

Coal per Oil in Coal Liquefaction : factorio

Coal Liquefaction produces 90 heavy oil, 20 light oil, and 10 petroleum every cycle. However, it does use 25 units of heavy oil, so it essentially produces 65 heavy oil. So, 65 (.5)+20 (.667)+10 = 55.84 units of petroleum are produced per cycle of Coal Liquefaction. Now, the next step is to figure out how much oil is equal to 1 unit of coal, in ...
