摘要
用差示扫描量热法(DSC)、热重法(TG)、微商热重法(DTG)分析研究了不同馏程的两种闪蒸油的预炭化沥青的热解行为。用偏光显微镜观察了两种预炭化沥青的炭化产物的光学显微结构,分析了两种预炭化沥青的性质。
The thermal destruction characteristics of condensation pitches of two differential distillation range's flash oil are studied with DSC,TG and DTG.Then,analysis the differential reason having some effect on the thermal destruction characteristics of two kinds of condensation pitches.The property of two kinds of condensation pitches is evaluated by optical microstructure of cokes obtained from condensation pitches.
