In Fischer‐Tropsch synthesis (FTS), a variety of hydrocarbons with different chain lengths are formed. The selectivities depend on the catalyst and the reaction conditions. Co‐feeding olefins allows changing the selectivity even outside the rules of the Anderson‐Schulz‐Flory distribution. In this work, ethene, propene, and 1‐butene were co‐fed to Co‐Mn‐catalyzed FTS to increase the olefin selectivity in the C 3 ‐ to C 8 ‐fraction. An increase of the CO reaction rate and oxygenate selectivity indicates that besides FTS also hydroformylation takes place. While the predominant reaction is the unwanted hydrogenation of the co‐fed olefins, this could in case of ethene be reduced by lowering the H 2 pressure.
