A multi-stage catalyst system is disclosed for the production of waxes in a Fischer-Tropsch process while producing relatively low quantities of methane. A first catalyst converts CO and H2 into olefins, while a second catalyst converts the olefin, additional hydrogen and CO into higher molecular weight paraffin.

A process for producing paraffinic hydrocarbons from carbon monoxide and hydrogen comprising: (a) introducing carbon monoxide and hydrogen into a reaction zone wherein the carbon monoxide and hydrogen contact in a first bed a first catalyst having a high olefin selectivity selected from the group consisting of Fe/Ce/Zn/K, Fe/Mn/K and Fe/Co/K; and (b) contacting the resulting olefin in a second bed with a second catalyst having a high selectivity for converting olefins to heavier paraffinic hydrocarbons selected from the group consisting of Ru/TiO2, Ru/SiO2 and Ru/Al2O3.
