摘要
煤沥青是以芳香族为主的结构很复杂的高分子化合物的混合体,碳含量高,是重要的炭材料工业原料,其高附加值利用备受关注。化学改性法可以从本质上对煤沥青分子结构进行调整,是其高附加值资源化利用的重要手段。简要介绍了煤沥青氧化、加氢、聚合、交联等化学改性方法及其高附加值应用。
Coal-tar pitch is a mixture of aromatic-based complex polymer compounds with high carbon content.It is an important industrial raw material for carbon materials,and its high value-added utilization has attracted much attention.The chemical modification method can essentially adjust the molecular structure of coal-tar pitch and is an important means for its high value-added resource utilization.The chemical modification methods of coal-tar pitch oxidation,hydrogenation,polymerization,crosslinking,etc.and their high value-added applications are briefly introduced.
