摘要：

Hierarchical structured alpha-Al2O3 is shown to be able to effectively disperse and immobilize iron species, in comparison with commercial alpha-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.
