Deposition behavior of iron catalysts during sulphidation were investigated using stainless-steel test-piece and I-MN as solvent. It was appeared that α-Fe_2O_3 which easily formed large particles by aggregation during the sulphidation. had relatively small amount of deposition on the test-piece and that γ-FeOOH dispersed in solvent had high oil yield and small amount of deposition in coal liquefaction reaction.
