Abstract

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.
