Fe-based Fischer Tropsch Synthesis of biomass-derived syngas: Effect of synthesis method

Abstract

Two 100Fe/4Cu/4K/6Zn catalysts were prepared using two different methods: coprecipitation or impregnation methods. The effect of the preparation methods on the catalyst structure, catalytic properties, and the conversion of biomass-derived syngas via Fischer–Tropsch synthesis was investigated. Syngas was derived from gasifying Southern pine woodchips and had the composition of 3.1% CH4, 11% CO2, 17%H2, 22%CO, and47%N2. The results show that the coprecipitated Zn-promoted catalyst had higher extent of reduction and carburization, which led to higher carbon conversion and C5+ selectivity of this CO2-rich syngas than the impregnated catalyst.
