Abstract: 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 asphaltene decrease.The higher the inertinite maceral content,the lower the conversion and oil yield.
