Linear α-olefin production with Na-promoted Fe-Zn catalysts via Fischer-Tropsch synthesis.

ABSTRACT: The production of linear alpha-olefins (α-olefins) is a practical way to increase the economic potential of the Fischer-Tropsch synthesis (FTS) because of their importance as chemical intermediates. Our study aimed to optimize Na-promoted Fe₁Zn_1.2O _x catalysts such that they selectively converted syngas to linear α-olefins via FTS at 340 °C and 2.0 MPa. The Fe₁Zn_1.2O _x catalysts were calcined at different temperatures from 350 to 700 °C before Na anchoring. The increase in the size of the ZnFe₂O₄ crystals comprising the catalyst had a negative effect on the reducibility of Fe oxides and the particle size of Fe₅C₂ during the reaction. The Na species in the catal
