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 H2 to hydrocarbons and possibly oxygenates thereof. In the process CO and H2 are 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.
Claims19
A two phase high temperature Fischer-Tropsch process wherein reactants in the form of CO and H2 are converted to products in the form of hydrocarbons and possibly oxygenates thereof by contacting CO and H2 with a precipitated iron catalyst in combination with a source of chromium as a catalyst promoter under high temperature Fischer-Tropsch conditions carried out in a fluidized bed reactor, wherein the reactants and the products are in a gas phase and the catalyst is in a solid phase.
