| 摘 要： | 煤沥青具有资源丰富、价格低廉等优点,但其残炭率低,可以通过改性来提高其残炭率。简要介绍了改性煤沥青的制备方法及近几年来国内外改性煤沥青的发展状况,并探讨了其机理。由于煤沥青组成复杂,并不能知道其确切的反应机理,只能根据测试结果提出其可能的改性机理。

| Abstract: | Coal tar pitch is abundant and cheap,but its carbon yield is low.The carbon yield can be improved by modification of coal tar pitch.The preparation method and the progress of modification of coal tar pitch in recent years are summarized.Furthermore,the mechanism of the modification of coal tar pitch is discussed.Although the exact mechanism of modification can not be known for its complex composition,the potential mechanism can be obtained through the test results. |
