摘要
初步探讨了活化剂的加入对煤沥青的焦化活性、沥青焦的结构、氧化活性和导电性的影响。实验结果表明 :活化剂改性后的煤沥青 ,固定碳含量提高。用这种煤沥青制得的沥青焦 ,其抗氧化性提高 。
The effects of activating agents on the caking ability of coal tar pitch and its derived coke's properties including structure,anti oxidization ability and electrical conductivity have been investigated.The results show that the fixed carbon in coal tar pitch modified with activating agent has been increased.Both the oxidation resistance and the electrical conductivity of the pitch coke can be improved when a suitable amount of activating agent is added in the coal tar pitch.
