Abstract

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 C3- to C8-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 H2 pressure.
