Abstract

The large-scale deployment of sustainable aviation fuel (SAF) is essential for achieving deep decarbonization in the aviation sector. Compared with biomass-derived routes that are constrained by feedstock availability and composition

aviation fuel synthesis via CO/CO

hydrogenation offers significant advantages in the efficient recycling and utilization of carbon resources. However

this process involves the multistep coupling of CO/CO

activation

C-C chain growth

and the selective construction of C

-C

aviation fuel-range hydrocarbons

resulting in a highly complex reaction network jointly governed by thermodynamics

kinetics

and mass transfer. This review systematically summarizes the reaction pathways and catalytic advances in aviation fuel synthesis via CO/CO

hydrogenation. Particular emphasis is placed on comparing the RWGS-FT

methanol-mediated pathways in terms of intermediate evolution and C-C bond formation mechanisms. The structure-performance relationships of Fe-based

Co-based

and metal-zeolite bifunctional catalysts in CO/CO

activation

carbonchain growth

and product structure regulation are comprehensively discussed. Furthermore

the synergistic effects of the spatial coupling between active sites and the diffusion of reaction intermediates on the selective formation of aviation fuel-range hydrocarbons are analyzed. Based on these discussions

three key scientific

challenges in CO/CO

hydrogenation to aviation fuel are identified: (i) thermodynamic-kinetic matching in multistep reaction networks

(ii) the limitations imposed by the Anderson-Schulz-Flory (ASF) distribution during carbon chain growth

and (iii) spatiotemporal matching of active sites and diffusion regulation of intermediates in bifunctional catalytic systems. Future research directions are proposed from the perspectives of mechanism-driven interfacial regulation

multiscale catalyst design

and catalyst-reactor collaborative optimization

providing guidance for the efficient and selective synthesis of sustainable aviation fuel via CO/CO

hydrogenation and its industrial implementation.
