The effect of properties of 12 kinds coals such as C‰, H/C ratio, O/C ratio, fuel ratio on liquefaction conversion and product yield has been investigated.
The main conclusions from this work are: 1. The linear correlation between carbon contents, fuel ratio of coals and liquefaction conversion did not recognized.
2. The yield of gaseous product are increased with decrease of carbon contents of coals. 3. Produced oil from the coals which have high value of H/C, contains high portion of light fraction (b.p-220°C).
