摘　　要：以乙炔为原料气,用工业化生产炉代替小型实验研究炉批量制备出了纳米碳管,产量为150g/h。TEM图和Raman光谱结果表明,纳米碳管管径均匀分布在20～30 nm间,具有很高的石墨化程度。同时,讨论了生产炉结构、工艺参数以及裂解温度、裂解时间和原料气流量对纳米碳管的影响。In this paper,carbon nanotubes were synthesized by the industry furnace instead of small study fur- nace using C_2H_2 as raw material with high yield of 150g/h.TEM and Raman spectrum showed that The diameter of products is 20～30 nm and carbon nanotubes have good quality.And a systemic discussion about the effect of tempera- ture,time,flow rate of source gas and the technical parameters on the products was carried out.
