Reducing methane production and increasing liquid yields in Fischer-Tropsch reactions
 A process for reducing methane formation and increasing liquid (C.sub.5.sup.+) yields in Fischer-Tropsch hydrocarbon synthesis processes of CO and H.sub.2 comprising adding one or more olefins to the reactor bed at a point below 10% of the distance from the top to the bottom of the reactor bed and above a point 10% above the bottom of the reactor bed to the top of the reactor bed in an amount sufficient to reduce said methane formation.
