Abstract in another language

The effects of structural promoters (ZnO, SiO2, and Al2O3) on the phase transformation during reduction and Fischer-Tropsch synthesis (FTS) of a FeCuK catalyst were investigated by in situ X-ray diffraction and the FTS catalytic performance was studied in a fixed-bed reactor. The reduction follows the path of Fe2O3/K2Fe22O34 → Fe3O4 → α-Fe. The addition of ZnO, SiO2, and Al2O3 delayed and prolonged the reduction. The iron carbides formed under reaction conditions were χ-Fe5C2 and ε-Fe2C. The presence of ZnO, SiO2, and Al2O3 favored the formation of χ-Fe5C2. ε-Fe2C is a more active phase. Besides, ε-Fe2C seems to favor the formation of CO2 and C5+ and χ-Fe5C2 benefits CH4 and C2–C4 products.
