The effect of Modification of Fischer-Tropsch Catalysts on the Synthesis of Higher C2+ Alcohols, Valuable Raw Materials for Sustainable Aviation Fuels
https://doi.org/10.18412/1816-0395-2025-12-32-39
Abstract
Data on the activity of Fe-containing Fischer-Tropsch catalysts doped with Cu, Co, and K deposited on attapulgite, as well as with different Cu:Fe ratios (3:17, 12:8 or 17:3), have been established in the synthesis of C2+ alcohols from synthesis gas (H2:CO=1; 2) to produce sustainable aviation fuel (225–300 °C, 30 bar). It was found that the joint introduction of Cu, Fe, Co and K provides a higher yield of C2+ alcohols, the selectivity of which increases with increasing proportion of Fe and temperature (H2:CO=1), reaching 90% over 3Cu17FeCoK/attapulgite at CO < 10% conversions. It is noted that the higher activity of 3Cu17FeCoK along the route of synthesis of C2+ alcohols is apparently associated with a higher content of highly dispersed phases of Fe0; Fe3O4 (XRD) and a uniform distribution of metals on the surface (TEM), providing effective interphase contact.
