In conclusion, the CO2 hydrogenation coupled with toluene alkylation to aromatic of jet fuel over Fe&3Z5 tandem catalysts shows great potential for the synthesis of SAF components. The Fe&3Z5 tandem catalyst contains three active sites (Fe3O4, Fe5C2 and acidic sites). CO2 and H2 undergo RWGS and FTS reactions in the Fe3O4 and Fe5C2 active sites of the iron-based catalyst in turn to form an olefin intermediate, which is then alkylated with toluene over the acidic site of the zeolite to produce aromatics of jet fuel. Low carbon number olefins were more readily alkylated with toluene at the acidic site of the Z5 zeolite. The proximity of the two components in a tandem catalyst has a significant modulating effect on the distribution of hydrocarbon products. The optimized catalytic system presented the CO2 conversion in particle mixing mode was 29.4% with the selectivity of aromatics of jet fuel up to 75.0%. Furthermore, the catalyst showed no significant deactivation in the 100 h lifetime experiment, displaying the advantages over using olefins directly as a alkylation agent. The present work demonstrates the feasibility of CO2 hydrogenation coupled with toluene alkylation for jet fuel aromatics synthesis over tandem catalysts and is an inspiration for the study of other related systems.
