A Simple, Inexpensive, Solventless Method for Preparation of Active Iron Fischer Tropsch Catalysts

Unsupported Fe-Cu-K-SiO₂ and Fe-Mn-K-SiO₂ Fischer-Tropsch catalysts have been developed using a novel co-precipitation method. This simple, dry-mix method produces precursor catalysts in about one-quarter the time it takes to prepare standard precipitated catalysts.  The physical and chemical properties of these catalysts compare favorably with iron catalysts described in the literature.
