- •
The roles of alkalis in iron-based Fischer-Tropsch synthesis catalysts were studied.
- •
In situ XRD and XPS were used to study effects of alkalis on the catalyst reduction.
- •
Alkalis strengthen Fe
O bonds of α-Fe2O3 in fresh catalysts.- •
Alkalis shift the FTS product distribution to heavy hydrocarbons.
