Abstract

In this work, the performance of the Fischer–Tropsch reaction over iron catalyst in three reactor configurations was theoretically studied and analyzed. Indeed, the control and the guidance of produced hydrocarbons composition were done using a new concept of membrane separation reactor. Our findings show that the composition can be imposed by the nature of the integrated membrane. Depending on the used membrane, the water gas shift reaction equilibrium can be shifted towards hydrogen production or towards carbon monoxide production and consequently, the H₂/CO ratio was changed in situ for giving olefins or paraffin according to our requirements specification. Finally, it was found that using a water permselective membrane can boost the composition to C₃–C₅ olefin compounds, whereas the separation of carbon dioxide can enhance the formation of paraffins.

Fischer-Tropsch合成在工业铁催化剂上生产的清洁烃分布的控制和定向新概念

摘要

在这项工作中，在理论上研究和分析了三种反应器配置下费托反应在铁催化剂上的反应性能。实际上，使用膜分离反应器的新概念完成了对生产的烃组成的控制和指导。我们的发现表明，该组成可以由整合膜的性质决定。取决于所使用的膜，水煤气变换反应的平衡可以朝着氢气生产或向一氧化碳生产转移，因此，根据我们的要求规格，就地改变了H ₂ / CO比值以得到烯烃或链烷烃。最后，发现使用水选择性渗透膜可以将组合物的碳含量提高到C ₃ –C _5。 烯烃化合物，而二氧化碳的分离可以增强石蜡的形成。
