Using once-through liquefaction, bituminous coals yielded 39-46 percent liquids, sub-bituminous coals yielded 38 percent liquids and lignite yielded about 36 percent liquids (see Figure 3). With vacuum bottoms recycle, liquefaction of various coals resulted in liquid yields of 55-60 percent for bituminous coals, 44-50 percent for sub-bituminous coals, and 47 percent for lignite.

Coal utilization - Coal utilization - Liquefaction: Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum. Therefore, conversion of coal into liquid fuels involves the addition of hydrogen.

Coal Liquefaction - an overview | ScienceDirect TopicsTraduire cette page

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 nitrogen and sulfur). There are three major methods of producing liquid fuels from coal ...
