ABSTRACT:
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 H.sub.2 into olefins, while a second catalyst converts the olefin, additional hydrogen and CO into higher molecular weight paraffin.
