Structuring of Reactors and Catalysts on Multiple Scales: Potential and Limitations for Fischer-Tropsch Synthesis

Structuring of catalysts and reactors increases the number of degrees of freedom and thus allows tailoring the design for each particular application. Thereby, transport processes can be intensified in order to increase the reactor productivity. This contribution illustrates concepts of structuring on different lengths scales for Fischer-Tropsch synthesis as example. On this basis the approach of multi-scale structuring is proposed in order to achieve an improved control of transport processes in chemical reactors.
