Study on Extraction Asphaltenes from Direct Coal ...

Direct coal liquefaction residue (DCLR) contains about 25% asphaltenes which are proved to be important precursors for preparing high value-added carbon materials. In this work, ionic liquids (ILs) were used as potential solvents to extract asphaltenes from DCLR, and a series of dialkylphosphate ILs, i.e., imidazolium-based, pyridinium-based, and ammonium-based, were synthesized and used to ...

Coal Liquefaction - Dadyburjor - - Major Reference Works ...

Coal liquefaction incorporates both an increase in the H/C ratio and removal of heteroatoms (S, N, O) and inorganic oxides (ash). Successful industrial direct liquefaction processes must incorporate both these steps, along with the transport of solid and slurry ‐ phase material in large – scale processing.
