摘　　要：为了合理利用煤液化油及优化煤液化油提质加氢工艺,以神华煤为例,对其进行煤炭直接液化BSU实验。将液化生产油进行实沸点切割,<300℃有9个窄馏分。测定了各个窄馏分在低温下的饱和蒸气压。重点考察了Clapeyron方程和Antoine方程对煤液化油窄馏分蒸气压与温度的回归计算。结果表明:神华煤液化油窄馏分的饱和蒸气压与温度的关系符合Clapeyron方程和Antoine方程,但Antoine方程的精度高于Clapeyron方程。To make better use of coal-derived oil and optimize upgrading process, obtained Shenhua coal-derived oil samples from continuous direct coal liquefaction test. Nine narrow fractions are gained by the true boiling point distillation from the samples,of which boiling point is lower than 300 ~C. The saturated vapor pressures （SVP） of the narrow fractions are measured at lower different temperatures. It is emphasized on the regression calculation between the SVP and temperature of the narrow fractions of the samples by the Clapeyron＇s and Antoine^s equation. The results show that, the relationship between the SVP and temperature accords with the two equations, and the former is more accurate.
