摘　　要：在0.1 t/d煤液化连续试验装置上对神华上湾煤进行煤液化试验,将得出的煤液化油产品经实沸点蒸馏切割成14个窄馏分.对于每一个馏分测定其在不同温度下的密度,得出密度随温度的升高而降低,且有很好的线性关系,通过理论推导得出体胀系数E和线性系数也呈线性关系.根据每一馏分在不同温度下的运动黏度,计算得出对应窄馏分的动力黏度,动力黏度随着温度的升高而降低,且符合Vogel关系式.Shangwan coal-derived oil samples were obtained from the 0. 1 t/d continuous test unit. 14 narrow fractions were gained by the true boiling point distillation. The specific density and dynamic viscosity of the narrow fractions were determined at different temperatures, and the relationships between these properties and the average boiling points were correlated. The specific density decreases with temperature rising according to a linear relation, and volume expansion coefficients are deduced from the linear coefficients. The kinetic viscosity decreases with temperature rising according to Vogel＇ s equation.
