改性煤沥青炭化产物结构和性能

Structure and properties of coke derived from the modified pitch

利用化学活性物质对煤沥青进行改性处理，研究了改性煤沥青炭化产物的结构和性能。研究结果表明，改性煤沥青炭化产物的显微结构根据化学活性物质的添加量的不同可是流动状、细镶嵌状和光学各向异性结构；适量的添加化学活性物质，可得到微晶发育良好，抗氧化性优良的沥青炭化产物。

A chemical active agent was selected to modify coal pitch. The structure and properties for coke derived from themedified pitch was studied. The results show that the microstructures depend on the quantity of the chemicaI active agent. A coke with excellent properties can be obtained by adding right amount of chemical active agent.
