摘要：基于低阶煤温和液化-炭化耦合工艺,主要研究了390-450℃液化温度条件下的产物分布特征,分析了所得液相产物和半焦的性质。结果表明,有机液相产率达23.44%-33.26%(干燥无灰基煤为基准),半焦产率达49.56%-68.72%(干燥无灰基煤为基准);所得液相产物水含量为1.30%-2.49%,不含固体颗粒,有机液相产物的正己烷可溶物含量达98.95%以上;所得半焦碳含量高达87.87%-93.45%(干燥无灰基),部分半焦产物具有强黏结性的特点,并且黏结性与其沥青质含量相关。
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.
