ABSTRACT:
According to the present invention there is provided the use of a source of chromium in combination with a precipitated iron catalyst in a high temperature Fischer-Tropsch process to convert CO and H2to hydrocarbons and possibly oxygenates thereof. In the process CO and H2are contacted with the source of chromium in combination with the precipitated iron catalyst in a high temperature Fischer-Tropsch reaction. The invention also relates to the use of a source of chromium in the preparation of a precipitated iron catalyst for use in high temperature Fischer-Tropsch process and to a precipitated iron catalyst suitable for use in a high temperature Fischer-Tropsch process which contains a source of chromium.
