费托催化剂在多孔网络中的扩散限制强烈影响其活性和产物选择性。尤其是小孔阻碍了反应物的扩散。为了克服扩散限制，研究了在催化剂中引入输运孔对反应速率和选择性的影响。结果表明，输运孔可以增加扩散长度，保持较高的反应速率和C5+选择性。总的来说，通过优化输运孔隙率可以提高产能。
Diffusional restrictions in the porous network of Fischer-Tropsch catalysts strongly affect activity and product selectivity. Especially small pores hamper the diffusion of reactants. In order to overcome the diffusion restrictions, the introduction of transport pores into the catalyst and the resulting effect on reaction rate and selectivities were studied. It was shown that transport pores allow for an increase in diffusion length, maintaining high reaction rate and C5+ selectivity. Overall, the productivity can be increased through optimization of the transport pore fraction.
