摘　　要：以椰壳炭、竹炭和木炭三种活性炭为载体,采用浸渍法制备炭负载金属镍的催化剂,考察其在废塑料裂解制备碳纳米管过程中的催化反应性能;采用X射线衍射、扫描电镜、透射电镜、拉曼光谱仪、同步热分析仪、比表面积分析仪等手段分析了催化剂和产物碳纳米管的形貌和结构。结果表明,椰壳活性炭为载体制备的镍基催化剂上碳纳米管产量最高、石墨化程度最好。以椰壳活性炭为载体制备的镍基催化剂为例,研究了反应温度和镍负载量对其催化性能的影响。A series of Ni based catalysts are prepared through impregnation method with coconut shell,bamboo charcoal and charcoal activated carbons as the support;their catalytic performance in the pyrolysis of waste plastics to produce carbon nanotubes was comparatively investigated.The structure and morphology of the catalyst and carbon nanotubes were characterized by X-ray diffraction,scanning electron microscope,transmission electron microscope,Raman spectroscopy,thermogravimetric analysis and nitrogen physisorption.The results show that carbon nanotubes with the highest yield and the best quality can be produced by using the nickel catalyst supported on coconut shell activated carbon(Ni/CSAC).In addition,the effect of reaction temperature and nickel loading on the catalytic performance of Ni/CSAC in the pyrolysis of waste plastics was considered.
