摘要
研究了沥青经溶剂处理制取针状焦原料的适宜条件,得出了芳脂比、溶剂比与精制沥青的QI含量和收率的关系。为利用煤沥青制取针状焦原料提供了有参考价值的基础数据。
The a suitable conditions in which needle coke crude material is produced with pitch by solvent treatment is touched upon. The relationship of the proportion of the aromatic hydrocarbon to the fat hydrocarbon, the proportion of solvent to QI content and the yield of refind pitch discussed. The basic data of making needle coke crude from coal pitch is provided.
