摘要/Abstract

摘要： 采用浸渍法，以纳米碳管（CNT）为载体，制备了Ni负载量为3.91%（质量分数）的Ni/CNTs催化剂。利用X射线衍射（XRD）、拉曼光谱、电感耦合等离子体发射光谱（ICP-OES）以及透射电镜（TEM）等技术对Ni/CNTs催化剂进行了表征。在连续流动状态下通过一系列实验考察了温度、压力、氢气量以及流速对Ni/CNTs催化苯乙炔选择加氢性能的影响，利用高效液相色谱仪HPLC对产品进行定性和定量分析。实验结果表明，催化剂Ni/CNTs对苯乙炔选择加氢反应具有一定的催化活性；反应的最佳温度为20℃；压力对产品收率影响显著，微正压对反应有利；最佳氢气量为24mL/min；产品收率随着反应液流速的增加而增大。

关键词: Ni/CNTs催化剂, 连续流动, 苯乙炔, 选择加氢

Abstract: The 3.91% Ni loaded Ni/CNTs catalyst was prepared with the support of carbon nanotubes by impregnation method. The catalyst was characterized using X-ray diffraction(XRD),Raman spectra,inductively coupled plasma optical emission spectrometry(ICP-OES)and TEM. The effects of temperature,pressure,hydrogen quantity and flow velocity on the Ni/CNTs catalyst for the phenylacetylene selective hydrogenation were studied under continuous flow conditions. The products were analyzed qualitatively and quantitatively by high performance liquid chromatograph(HPLC). The results verified the catalytic activity of Ni/CNTs catalyst. The optimum reaction temperature was 20℃,and the optimal hydrogen flow was 24mL/min,while the yield of product styrene increased with flow velocity but decreased with pressure.

Key words: Ni/CNTs catalyst, continuous flow, phenylacetylene, selective hydrogenation
