| 摘 要： | 用TGA对煤沥青的热失重过程进行了研究,分析了煤沥青的热解缩聚特征,并对中温沥青和改质沥青热解缩聚行为进行了比较,研究了升温速率对煤沥青热解缩聚的影响,发现快速升温使煤沥青组份更多地分解逸出,不利于提高煤沥青的结焦值。

| Abstract: | The pyrolysis of coal-tar pitches has been studied using TGA in ter ms of thermal weight loss with an aim of revealing the characteristics of pyroly sis condensation of coal-tar pitches. For comparison, the pyrolysis of two diff erent types of pitches, medium pitch and modified pitch, are studied. The influe nces of heating rate on the pyrolysis condensation of coal-tar pitches are high lighted. It has been found that higher heating rate results in severe decomposit ion of coal-tar pitches that leads to more gaseous constituents, and is unfavou rable to the enhancement of coking value of coal-tar pitches. |
