Cs promoted Fe5C2/charcoal nanocatalysts for sustainable liquid fuel production

Abstract

Cs promoted Fe₅C₂/charcoal nanocatalysts bearing small iron carbide particles of 8.5 and 14 nm were prepared through a simple melt-infiltration process and a wetness impregnation method; the resulting materials showed very high CO conversion (>95%) and good selectivity, especially at Cs/Fe = 0.025, resulting in a high liquid oil productivity (∼0.4 g_liq g_cat⁻¹ h⁻¹) in high-temperature Fischer–Tropsch synthesis.
