| Abstract: | This paper reviews the functions and kinds of solvent in coal liquefaction. It is founded that solvent have many functions such as disolving, swelling, dispersing and diluting coal particles and preventing the free radical from polymerizing. The paper mainly discusses hydrogen donor solvent which can provide and transfer active hydrogen; It can be classified as common solvent which is used for industry or research, heavy oil such as coal tar, residue and wasted plastics and rubbers which is meaningful for economizing resources and improving environment when they are coprocessed with coal. |
