摘要
采用溶剂絮凝法和离心分离法对煤焦油进行净化处理，以净化煤焦油为原料制备了净化煤沥青，比较了净化沥青和未净化沥青的结构性质差异，并研究了两类煤沥青的炭化行为特征。
The purification treatment of coal tar was carried out using the solvent flocculationand centrifugalization. Purified coal -tar pitch was prepared form purfified coaltar. Thestructures and properties of the purified pitch and unpurified pitch were investigated,The carbonization behavior of two kinds of coal -tar pitchs was characterized.
