Abstract—The structure parameters of hydrogenation products were analyzed in relation to the composition
of oil and coal (intrinsic) paste-forming agents used in the process of coal hydrogenation under a low pressure
of hydrogen (6–10 MPa). It was found that the structure characteristics of liquefaction products essentially dif-
fered at close values of the structure unsaturation parameter 
; this was likely due to a difference in the material
composition of solvents (other than aromatic structures).
