Optimization of supported iron-based Fischer-Tropsch catalysts for higher alcohol production
Poster presented at 53. Jahrestreffen Deutscher Katalytiker - GEATS, Weimar, virtuell, 11.-13.3.2020
This study addresses the fundamentals of upscaling of iron-based Fischer-Tropsch catalysts for higher alcohol production. Therefore, Al2O3 powders of different particle size and modification were impregnated by different iron precursors under a variation of impregnation conditions. The supported iron catalysts were tested regarding conversion and selectivity. Conclusions are drawn on appropriate catalyst-support interactions by the choice of support and precursor materials as well as on optimized impregnation and Fischer-Tropsch synthesis conditions. The gained knowledge is the starting point for the production of different supported and structured catalysts.
