Abstract

Abstract

The distribution of products was preliminarily studied based on a process of low rank coal mild liquefaction at 390-450 ℃ coupled with carbonization. The characteristics of liquid product and semi-coke were analyzed. The results showed that the organic liquid product yield is 23.44%-33.26% (daf, coal) and the semi-coke yield is 49.56%-68.72% (daf, coal). The water content of liquid product is 1.30%-2.49%. The n-hexane soluble content of organic liquid product is higher than 98.95% with no solid particles in liquid product. The carbon content of semi-coke obtained is 87.87%-93.45% (daf), some semi-cokes have the characteristics of strong caking property. There is a close correlation between caking property and asphaltene content of semi-coke.
