摘　　要：对不同惰质组分含量的上湾煤样进行了高压釜煤液化实验。在反应温度440～465℃,氢初压7～11 MPa条件下,研究了5种不同惰质组含量的上湾煤的液化性能。结果表明:在反应温度为440～465℃内,随着温度的升高,除惰质组含量最高的5号煤样在温度高于465℃时转化率开始下降以外,其余不同惰质组含量的4种煤的转化率、油产率、气产率和氢耗均随着温度的升高而增加,沥青烯产率随温度的升高而减小;随着氢初压的增加,不同显微组含量的煤的转化率和油产率增加,沥青烯产率减小。惰质组含量越高,煤的转化率和油收率越低。The liquefaction experiments of five Shangwan coals with different inertinite content were carried out in a high pressure autoclave. The effect of reaction temperature ranging from 440 ℃ to 465 ℃ and initinal hydrogen pressure from 7 MPa to 11 MPa on the hydroliquefaction of five coals were investigated. The results show that the conversion,oil and gases yield, hydrogen consumption of 1 # to 4 # coal increase with the rise of temperature, meanwhile asphaltene decrease between 440 ℃ and 465 ℃, conversion of 5# coal decrease when the temperature is higher than 460 ℃. Conversion rate, oil and gases yield, hydrogen consumption of coal with different inertinite content increase with the increase of initial hydrogen pressure while asphahene decrease. The higher the inertinite maceral content, the lower the conversion and oil yield.
