摘要：
The hydrothermal method was used in order to prepare Fe-Co-Mn nanocatalysts. The prepared specimens were evaluated for the CO hydrogenation reaction. The impact of different kinds of supports such as Al2O3, SiO2, ZSM5, TiO2, MgO, ZSM5-Al2O3, ZSM5-TiO2, Al2O3-TiO2, Al2O3-SiO2, SiO2-ZSM5 and Al2O3-MgO on the behavior and structural characteristics of the Fe-Co-Mn ternary nanocatalysts was investigated. Evaluation of these various supported samples was performed under the same process conditions. Al2O3-supported sample showed better performance for light olefin production chosen as an optimum sample. Furthermore, the influence of a change of support type on the rate of surface reactions was studied. The impact of operating parameters was also investigated, with the conditions of T = 623 K, P = 2 bar and H-2/CO = 2 determined as the optimum reaction conditions. Catalyst characteristics were defined using a variety of methods. (c) 2021 Society of Chemical Industry (SCI).
