WebMay 15, 2024 · During catalyst activation and reaction, different iron phases, including metallic iron (Fe°), iron carbides (FeC x ), and iron oxides (Fe 2 O 3 and Fe 3 O 4) are formed and coexist. Until now, the nature of the active phase and the interplay between different phases has not been elucidated. WebAbstract. Fischer–Tropsch (FT) synthesis is a heterogeneous catalytic process that converts biomass-derived syngas (mixture of CO and H 2) to synthetic liquid fuels and valuable chemicals. FT synthesis has received renewed interest in recent years due to the necessity to decrease global dependency on fossil fuels. flag football tucson
