In order to obtain the fundamental data related to the heat transfer in acoal liquefaction process, the thermal conductivity of fractions in a recycle oil were measured at various temperature by using the transient hot wire method, where the fractions were prepared into 16 boiling fractions by centrifugal molecular still.<BR>Then, the following results were obtained.<BR>i) Thermal conductivity decreases as increasing temperature.<BR>ii) The correlation between thermal conductivity and A.P.I. gravity as mentioned in Gray's work can not be observed clearly.<BR>In addition, relationships among A.P.I. gravity, distilled temperature of fractions and average molecular weight were presented.
