椰壳纤维制备活性炭纤维的研究

Study on preparation of activated carbon fiber from coconut shell fibers

本文以椰壳纤维为原料,采用正交试验方法研究了（NH4）2HPO4作为活化剂,经预处理、炭化和活化过程制备活性炭纤维,其比表面积达到1268.1m^2.g^-1,含有一定量的中孔孔结构,主要集中在2-4nm。通过对比分析,得出了各反应条件对反应产物性能的影响,并对活化机理进行了分析。

Based on orthogonal experimental design,activated carbon fibers with high specific surface area 1268.1m^2·g^-1 and abundant mesopores（2-4nm） was prepared from coconut shell fibers through pre-oxidation,carbonization and activation.The chemical agent was（NH4）2HPO4.Effects of reaction parameters on product properties were obtained through comparison and analysis.The activation mechanism is also discussed on the basis of experiments.
