摘要

摘要: 采用AlCl₃作为催化剂,在633~1873 K和一定压力下对煤焦油进行催化炭化,得到催化炭化焦,并对其进行了高温处理。利用热重,X射线衍射,拉曼光谱和偏光显微镜表征催化炭化焦的聚合程度,微观结构和光学织构。结果表明,AlCl₃显著地加速了煤焦油的聚合并使之发生了脱氢反应,在673 K即可以得到具有高残炭率的焦。其中,AlCl₃的存在可以得到具有海岛状结构(即中间相微球分布于各向同性炭中间,且各向同性成分并存)的催化炭化焦。

Abstract: The polymerization and carbonization of coal tar was carried out at different temperatures from 633 to 1873 K using aluminium trichloride as catalyst.The polymerization degree, microstructures and optical texture of samples were analyzed by thermogravimetry, X-ray diffraction, Raman spectroscopy and polarized light microscopy.Results indicated that aluminium trichloride accelerated dehydrogenation during the polymerization of coal tar, and increased the toluene-insoluble fraction and carbonization yield.The presence of aluminium trichloride in the polymerized coal tar affected the microstructure of the coke by the formation of a quasi-isotropic structure.
