Title
A new and direct preparation method of iron-based bimodal catalyst and its application in Fischer–Tropsch synthesis
Abstract

A bimodal iron-based catalyst was prepared by a new one-step impregnation method. The active components were used as the “brick” to directly build the small pores inside the large pores of support, which was quite different from the previous bimodal catalysts that were prepared once more on a bimodal support. Comparing with the unimodal catalysts and conventional co-precipitated catalyst, the prepared bimodal catalyst exhibited excellent activity in Fischer–Tropsch synthesis due to the improved active metal dispersion and fastened diffusion efficiency. This preparation method is much simpler than the previous methods and can be extended to prepare various bimodal catalysts with different chemical compositions.

Graphical abstractThrough one-step impregnation, an iron-based bimodal catalyst was prepared by directly using the active components for building up small pores inside the large pores of support, which exhibited superior activity in Fischer–Tropsch synthesis.
