ABSTRACT:
A Fischer-Tropsch catalyst comprising iron and at least one promoter is prepared via a method which comprises the preparation of a high purity iron precursor and which uses a nominal amount of water in the catalyst production. The catalyst particles prepared with the high purity iron precursor have an essentially spherical particle shape, a relatively narrow particle size distribution range, and a high surface area.
