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。 It is pointed out that the molten Fe-Co catalyst has high activity for Fischer-Tropsch synthesis reaction, low reaction temperature and less CO2 content in the product. The added metal Co melts and forms a solid solution with Fe 3 O 4. After H 2 and N 2 reduction and activation, Co atoms are uniformly distributed in the α-Fe lattice and the α-Fe unit cell parameters become larger. Fe-Co catalyst reduction process after the reaction of α-Fe more. Fe_4O_4 phase less, promote the - Reactor activity increased, inhibiting the transformation reaction, reducing the product C0_2 content.
