摘要/Abstract

摘要： 利用FTIR光谱分析和分峰拟合的数学方法对AlCl₃改性净化沥青的芳香指数（I_ar）和支链化指数（CH₃/CH₂）进行了研究；利用偏光显微镜研究了改性净化沥青的液相炭化产物及其煅烧物的光学显微结构；利用XRD研究了炭化产物的炭微晶分布情况。结果表明，AlCl₃改性净化沥青的I_ar和CH₃/CH₂指数分别为0.6388和0.4329；液相炭化时间对改性净化沥青的液相炭化产物的微观结构影响明显。通过XRD及分峰拟合的方法发现，1000℃煅烧处理后的液相炭化产物中趋于规整炭微晶含量I_g与液相炭化时间呈现很好的线性关系。可以预测，以AlCl₃改性净化沥青为原料，适当延长液相炭化时间可以制备出微观结构良好、易于石墨化的优质中间相沥青焦。

Abstract: Combined with FTIR spectrum analysis and curve-fitting method were used to calculate the aromatic index (I_ar) and branch chain index (CH₃/CH₂) of refined pitch modified by AlCl₃. Optical microstructure of liquid phase carbonization product and its calcination product were studied by optical microscope. The distribution of carbon crystalline in calcinated product was determined by XRD. The results show that, the refined pitch modified by AlCl₃has the I_ar and CH₃/CH₂ index of 0.6388 and 0.4329, respectively. The holding time of liquid phase carbonization present an significant impact on the microstructure of carbonization product. Coupled with XRD analysis and curve-fitting method reveals that, it shows the content of ordered crystallite structure (I_g) and holding time of calcinated product present a good linear relationship. It can be predicted that,extension the holding time can takes a positive role on the microstructure of high quality pitch based coke and easy to graphitization, using the refined modified pitch as the raw material.
