Using a resonance agitation reactor the effect of solvent on liquefaction of Chinese Yangcun bituminous coal under H₂ or N₂ under 7.0 MPa (cold) was studied. The results show that chain hydrocarbon and mono-ring series compounds are not good solvents. For the same series solvents, partly hydrogen aromatic compounds are the best solvents, followed by aromatic compounds with chain and aromatic compounds. Cycloparaffin and phenols are bad solvent. Decalin and methylnaphthalene do not change H₂ into active hydrogen because coal conversion is similar under H₂ or N₂. Tetralin can change H₂ into active hydrogen.
