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.

乙烯、丙烯和 1-丁烯共进料钴锰催化费托合成

在费托合成 (FTS) 中，会形成多种链长不同的烃。选择性取决于催化剂和反应条件。即使在 Anderson-Schulz-Flory 分布规则之外，共进烯烃也可以改变选择性。在这项工作中，乙烯、丙烯和 1-丁烯共同加入到 Co-Mn 催化的 FTS 中，以提高 C ₃ - 至 C ₈ -馏分中的烯烃选择性。CO 反应速率和含氧化合物选择性的增加表明，除了 FTS 之外，还发生了加氢甲酰化。虽然主要反应是不希望的共进烯烃加氢，但在乙烯的情况下，这可以通过降低 H ₂压力来减少。
