Excellent activity for coal liquefaction and low hydrogen consumption of deposited iron sulfide catalyst for coal liquefaction was reported in our privious report. Successive gpc and type analysis were conducted, to see characters of Wandoan coal's liquefied fractions (Benzene soluble fractions (BS) and benzene insoluble and pridine soluble fractions (BI-PS)) by deposited iron sulfide catalyst and three reference catalysts (iron sulfide powder, Ni-Mo/Al<SUB>2</SUB>O<SUB>3</SUB> and ZnCl<SUB>2</SUB>). The molecular weight distributions turn lower in the following order, iron sulfide powder≅ deposited iron sulfide > Ni-Mo/Al<SUB>2</SUB>O<SUB>3</SUB>>ZnCl<SUB>2</SUB>. The polarity of BS turn weaker in the same order as the molecular weight distributions turned.<BR>The conclusions are as follows:<BR>1) there is few fundamental difference between liquefied Wandoan coal structure by deposited iron sulfide catalyst and that by powdowered iron sulfide catalyst.<BR>2) low hydrogen consumption using two iron sulfide catalysts is due to the fact that liquefied Wandoan coal structure is similar to that of original Wandoan coal.
