Coal liquefaction: A research and development needs

2019-11-16  Abstract. Volume II of this report on an assessment of research needs for coal liquefaction contains reviews of the five liquefaction technologies---direct, indirect, pyrolysis, coprocessing, and bioconversion. These reviews are not meant to be encyclopedic; several outstanding reviews of liquefaction have appeared in recent years and ...

EXPLORATORY COPROCESSING RESEARCH

Recent studies show that mild hydrothermal treatment of an Illinois #6 coal substantially enhanced conversion into soluble products. For instance the convertibility of an Illinois No. 6 coal into toluene-soluble products increased from - 35% to almost 70% when the coal was treated for 30 minutes with water at 250 "C under nitrogen, and then
