Air Carbon Recycling for Aviation Fuel Technology

4AirCRAFT’s ultimate goal is to develop a next generation of stable and selective catalysts for the direct CO2 conversion
into liquid fuels for the aviation industry, enabling the synthesis of sustainable jet fuel. 4AirCRAFT will overcome the current
challenges by combining three main reactions into one reactor to increase the CO2 conversion rate and reduce energy
consumption. 4AirCRAFT technology will produce sustainable jet fuel at low temperature (below 80 ºC), contributing to a
circular economy and leading to a decrease in GHG and reduced dependence on fossil fuel-based resources.
In order to achieve this goal, we will move beyond the SoA by precisely integrating and taking advantage of biocatalysts,
inorganic nanocatalysts, electrocatalysts, and their controlled spatial distribution within application tuned catalyst carrier
structures. These catalyst carrier structures will be based on metal-organic frameworks and engineered inorganic scaffolds
with hierarchical porosity distribution. This will unravel the activity of catalytic active phases and materials based on earth abundant elements allowing us to achieve high CO2 conversion percentages and selectivity towards jet fuels (C8−16). By
achieving this we will be able to circumvent the need for Fischer–Tropsch synthesis, that is unselective for the synthesis of
fuels, therefore eliminating further steps for hydrocracking or hydrorefining of Fischer–Tropsch waxes. In terms of inorganic
catalysts, size and shape of metal NPs, metal clusters, and single atoms at the surface of catalyst carrier structures will be
developed, and precise structure-performance-selectivity relationships will be established. In terms of biocatalyst, special
emphasis will be given to assure the long-term stability of deployed enzymes through programmed anchoring and shielding
from detrimental reaction conditions. Together application tuned catalyst carrier structures will be employed to steer
selectivity towards C8−16 molecules.
