Catalytic performance in fixed-bed and bubbling fluidized-bed reactor during Fischer-Tropsch synthesis on the iron-based catalysts

Fischer-Tropsch synthesis (FTS) for olefin production from syngas was investigated on the four different iron-based catalysts in a fixed-bed and a bubbling fluidized-bed reactor. The catalysts were prepared by wet-impregnation using Al₂O₃, SiO₂ and iron ore (FeOx) with active components of Fe, K and (or) Cu, and K/FeCuAlOx catalyst was prepared by co-precipitation method. The impregnated K/FeOx catalyst is found to be one of the promising catalysts to be applied in bubbling fluidized-bed reactor for high temperature FTS reaction due to its high resistance to catalyst attrition with high catalytic performance.
