摘要/Abstract

摘要： 制备了高比表面积的椰壳活性炭,对其结构性质进行了表征并测定了以椰壳活性炭为电极材料的双电层电容器的充放电性质和循环伏安性质.实验结果表明:以椰壳活性炭为电极材料的双电层电容器具有良好的充放电性能,电极比电容达164 F/g.以椰壳活性炭为吸附剂测定了NH₃、CO₂、CH₄、N₂、O₂和H₂在298K的吸附等温线.椰壳活性炭对不同气体的吸附性能存在很大差异,其对NH₃的吸附远远大于对CO₂、CH₄、O₂、N₂和H₂的吸附.以平衡吸附量的比值为参考,椰壳活性炭是适用于NH₃/N₂、NH₃/O₂及NH₃/空气这些气体混合物中NH₃吸附分离的优良吸附剂,可用于NH₃/CH₄气体混合物中NH₃的吸附分离并具有吸附分离CO₂/N₂、CO₂/O₂及CO₂/空气这些气体混合物中CO₂的潜力.

Abstract: Activated carbon with high specific surface area was prepared from coconut shell charcoal(CsAC), the structural properties of which were measured. The electrochemical performances of electric double-layer capacitor (EDLC) with CsAC as electrode material were investigated, including cyclic voltammetric and constant current charge/discharge properties. Results showed that EDLC had good charge/discharge performance and the specific capacitance of CsAC reached 164 F/g. Adsorption isotherms of NH₃, CO₂, CH₄, N₂, O₂ and H₂ on CsAC were measured at 298K. Considerable difference among the adsorption capacities toward different gases was observed and NH₃ was adsorbed much more than CO₂, CH₄, N₂, O₂ and H₂. According to adsorption amount ratio of two gases, it was concluded that CsAC was a very good adsorbent for the separation of NH₃ from its mixtures such as NH₃/N₂,NH₃/O₂ and NH₃/air. CsAC was also suitable for the separation of NH₃ from its mixture of CH₄,as well as for the separation of CO₂ from its mixtures of O₂ or N₂ or both.
