AlCl3改性净化沥青的液相炭化
Liquid phase carbonization of refined pitch modified by AlCl3
摘要
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 AlCl3 has 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.关键词
