Hierarchical structured α-Al2O3 is shown to be able to effectively disperse and immobilize iron species, in comparison with commercial α-Al2O3. After promotion using an appropriate amount of sulfur, iron catalysts exhibit not only enhanced Fischer-Tropsch synthesis activity and selectivity toward lower olefins, but also increased resistance against carbon deposits.
与商业α-Al2O3相比，分级结构的α-Al2O3能够有效地分散和固定铁物种。在使用适量硫进行促进后，铁催化剂不仅表现出增强的费托合成活性和对低级烯烃的选择性，而且还提高了抗积碳性能。
