The complex reaction mechanism of iron-based Fischer-Tropsch synthesis comprises of manifold primary and secondary reaction pathways. Within this work, an experimental setup for spatially-resolved measurements on promoted iron-based Fischer-Tropsch catalysts is presented, allowing for a general study of the influence of operating conditions and promotion as well as of the influence of secondary reactions on product selectivity. It was found that, depending on catalyst composition, considerable hydrogenation of 1-alcohols and olefins occurs, while no considerable influence of reinitiation of chain growth on product distribution could be found.

费托合成中的空间分辨反应曲线——操作条件的影响和铁基催化剂的促进作用

铁基费托合成的复杂反应机理包括多种初级和次级反应途径。在这项工作中,提出了对促进的铁基费托催化剂进行空间分辨测量的实验装置,允许对操作条件和促进的影响以及二次反应对产物选择性的影响进行一般研究。发现,取决于催化剂组成,1-醇和烯烃发生相当大的氢化,而没有发现链增长的重新引发对产物分布的显着影响。
