10.5. Indirect Liquefaction Processes | netl.doe.gov

Indirect coal liquefaction requires first gasifying the coal into a syngas. Therefore, while direct coal liquefaction (DCL) takes coal directly into a liquid phase, indirect coal liquefaction (ICL) consists of two major steps: (a) gasification to produce a synthesis gas (syngas); and (b) conversion of the carbon monoxide (CO) and hydrogen (H 2) in the syngas to a range of hydrocarbon fuels ...

Coal Liquefaction is the process of converting coal to liquid fuels. Coal Liquefaction Definition. The process of coal liquefaction creates synthetic liquid fuels from solid coal as substitutes for various petroleum products. There are two types of liquefaction - direct and indirect Williams R. H., Larson, E. D. (December 2003). A comparison of direct and indirect liquefaction technologies for ...

Coal Liquefaction - Infinite Heavy Oil? : factorio - reddit

(thats a bit over 1,5 blue belts) if you were to produce this purely from coal liquefaction you would consume about 2 240 coal per second (Thats 56 blue belts) and of course you would need some more since you need to make steam for the process and you also need some sulfuric acid for batteries and processing units.

0.17 Coal Liquefaction is basically a productivity increase process if used to make solid fuel with similar issues as prod modules. Tip As you may know, 0.17 tweaked how coal liquefaction worked, so that the oil products are mostly heavy oil, some light oil, and a bit of p. gas, while still requiring 10 pieces of coal and 3/8ths of coal in ...

Coal liquefaction - Energy Education

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, ...
