Monometallic Fe and bimetallic Ru–Fe supported catalysts were prepared by impregnation method and tested in Fischer-Tropsch synthesis (F-T). Their physicochemical properties were characterized by BET, SEM-EDS, FTIR, XRD, H₂-TPR, TPD-NH₃ techniques. The catalytic activity tests showed that the activation process has a huge impact on the reactivity properties in the studied process. The most active system in F-T reaction was 40%Fe/Al₂O₃–Cr₂O₃ catalyst which exhibited CO conversion equal 89.9% and the selectivity towards liquid product of 66.6%. The liquid products obtained in F-T process on 40%Fe/Al₂O₃–Cr₂O₃ consisted mainly of linear (76.8%), branched (17.7%) and unsaturated (5.5%) hydrocarbons. The chain growth probability in F-T process was estimated using an Anderson-Schulz–Flory distribution of obtained liquid product for all tested catalysts. The calculated α value for the most active catalyst was 0.76. The activity results indicate that iron carbides formed during activation process affects on the catalytic activity and selectivity of the iron catalyst during F-T synthesis. The activity measurements showed that the activity of the iron supported catalysts depends strongly on the catalyst phase composition and their acidic properties. XRD results confirmed that the most active catalyst in the investigated process exhibited the highest concentration of iron carbides phases on its surface.

单金属铁和双金属Ru-Fe负载的催化剂是通过浸渍法制备的，并在费托合成（FT）中进行了测试。通过BET，SEM-EDS，FTIR，XRD，H ₂ -TPR，TPD-NH ₃技术表征了它们的理化性质。催化活性测试表明，活化过程对所研究过程的反应性具有巨大影响。FT反应中活性最高的体系是40％Fe / Al ₂ O ₃ -Cr ₂ O ₃催化剂，其CO转化率等于89.9％，对液体产物的选择性为66.6％。FT过程中在40％Fe / Al ₂ O ₃ -Cr ₂ O上获得的液体产品_3个主要由线性烃（76.8％），支链烃（17.7％）和不饱和烃（5.5％）组成。使用获得的所有测试催化剂的液体产品的Anderson-Schulz-Flory分布估算FT过程中的链增长概率。活性最高的催化剂的计算出的α值为0.76。活性结果表明，活化过程中形成的碳化铁会影响FT合成过程中铁催化剂的催化活性和选择性。活性测量表明，铁负载催化剂的活性强烈取决于催化剂相的组成及其酸性。XRD结果证实在所研究的过程中最具活性的催化剂在其表面上表现出最高浓度的碳化铁相。
