一种使用硫生长促进剂大量制备纳米碳纤维的方法
摘要：
一种使用硫生长促进剂大量制备纳米碳纤维的方法,以苯、CH4、C2H2为碳源,以二茂铁、Ni(Co)4为催化剂,以氢、氦、氮气为载气,以含硫化合物如噻吩、H2S为生长促进剂,并且控制碳源与载气的摩尔比在0.05～0.075,碳与硫摩尔比为40～100∶1,催化剂与碳源的摩尔比为0.03～0.085;将含硫化合物碳氢化合物与催化剂在气态下充分混合,被载气匀速带入反应区,在反应区中保留0.5～0.075S,在1373K～1473K下生长纳米碳纤维。本发明产品收率高,成本低,可实现工业化生产。
摘要（英）：

By using benzene,CH4, C2H4 as carbon source, ferrocene and Ni(CO)4 as catalyst, H2, He or N2 as carrier gas, and sulfur containing compounds such as thiophene and H2S, as growth promoter, and throughcontrolling the mole ratio between carbon source and carrier gas to 0.05-0.075, that between carbon and sulfur to 40-100, and that between catalyst and carbon source to 0.03-0.085, the sulfur containing compound,the hydrocarbon and the catalyst are mixed fully and the mixture is carried by the carrier gas homogeneously to reaction area to maintain for 0.075-0.5 s wherein, and nanometer carbon fiber is grown at 1373-1473K. The present invention has high yield and low cost and is suitable for industrial production.
