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 suitable conditions for preparing needle coke raw materials by solvent treatment were studied. The relationship between the aromatics ratio, the solvent ratio and the QI content and the yield of refined asphalt was obtained. It provides the basic data with reference value for making needle coke raw materials from coal tar pitch.
