NEDOL coal liquefaction process has the technical advantage of various coal processing because the solvent quality such as aromaticity (fa) can be controlled at the hydrotreatment stage. At a same reaction condition, degree of the fa decreasing after the hydrotreatment varied with a source coal of the solvent recycled in a 150t/d pilot plant. The variation in the degree of the fa decreasing resulted from composition in aromatic compounds of the solvent because methyl-naphthalenes was more hydrogenated than a pyrene in the solvent hydrotreatment. Activity loss of the catalyst did not appear as the source coal of the solvent was changed. The hydrogenation reaction resulting in the fa decreasing followed first order kinetics with an activation energy of 15〜17kcal/mol in an experimental solvent hydrotreatment.
