Xinjiang Heshituoluogai coal contains about 36% volatile, 15% ash, less than 1% sulfur. And the H/C and O/C are about 1, higher than general coals, indicating that the coal belongs to young low rank coal. Classification diagram of structure-chemical index of coal sample shows that the performance of direct Coal Liquefaction is poor. Bulk density of the coal sample is 750 kg/m3, and true density is 1470 kg/m3, angle of repose is 16.88?, ignition point is 334 ?C. Specific heat of the coal sample is smaller, and its variation with temperature is a parabolic relationship. Mineral composition of ash mainly consists of SiO2, Al2O3 and Fe2O3, accounting for 43.96、30.36 and 8.6%individually. The coal tar, pyrolysis water, dry distillation gas and semicoke are about 11.6,18,7 and 63.4% respectively. And the main ingredients of retort gas are CH4, C2H6, H2, CO2 and CO, and harmful gas H2S contents 0.19% only. Basic properties of pyrolysis oil shows that coal tar oil is lighter and better, and is of poor low-temperature fluidity. The four component analysis shows that the coal tar still belongs to a heavy coal tar.
