低阶煤温和液化-炭化耦合转化过程及产物性质
Low rank coal mild liquefaction coupled with carbonization and its products
摘要
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.关键词
