摘要
介绍了煤系针状焦用原料的要求及调制方法,讨论了2种工业上原料精制的工艺,并重点阐述了国内外对原料的组分、反应性、软化点、流变性、残炭值和结晶度等方面的改性研究进展。在此基础上对煤沥青调制研究在国内的发展前景进行了展望。
The requirements and modulation methods of raw materials for coal needle coke is introduced.Two kinds of raw material refining processes in industry are discussed.Highlight the technical development of raw materials properties such as components,reactivity,softening point,rheology,residual carbon value and crystallinity at home and abroad.The development prospects of coal tar pitch modulation in China is forecasted.
