摘要
指出熔融Ｆｅ－Ｃｏ催化剂对费－托合成反应具有活性高、反应温度低，产物中ＣＯ２含量较少的特点。加入的金属Ｃｏ熔融后与Ｆｅ_３Ｏ_４生成固溶体，经Ｈ_２、Ｎ_２还原活化后，Ｃｏ原子均匀地分布在α－Ｆｅ晶格中，并使α－Ｆｅ晶胞参数变大。Ｆｅ－Ｃｏ催化剂还原后反应过程中α－Ｆｅ相较多。Ｆｅ_４Ｏ_４相较少，促使－托反应活性提高，抑制了变换反应，减少产物中的Ｃ０_２含量。
This paper reports the research results of F-T synthesis on fused Fe-Co catalyst which is characteristic of high activity,low reaction temperature and little content of CO2 in products during F-T reaction.Fused Co was combined with Fe3O4 to form solid solution, and after the catalyst is reduced with H2 and N2, Co atoms are equally distributed in lattice of α-Fe,and lattice parameter of α-Fe increased. During F-T reaction, α-Fe phase of reduced catalyst of Fe-Co is more,and Fe3O4 phase is less,which contributed to the activity of F-T reaction and inhibits shifting reaction,so that CO2 content of products are decreased.
