Technology to convert syngas into aviation fuel is described. Some variations provide a process comprising: providing a starting syngas stream comprising Hand CO; purifying the syngas feed stream, if necessary; feeding the clean syngas stream to an alcohol-synthesis reactor, to catalytically convert syngas to a C-Cmixed-alcohol stream; feeding the C-Cmixed-alcohol stream to a dehydration reactor, to catalytically convert C-Cmixed alcohols to C-Cmixed olefins; feeding the mixed olefins to an oligomerization reactor, to catalytically convert the C-Cmixed olefins to C-Cmixed hydrocarbons; feeding the C-Cmixed hydrocarbons and hydrogen to a hydrogenation reactor, to catalytically hydrogenate C═C double bonds within the C-Cmixed hydrocarbons, thereby generating stabilized C-Cmixed hydrocarbons; and recovering the stabilized C-Cmixed hydrocarbons as aviation fuel. In preferred embodiments, the aviation fuel is sustainable aviation fuel (SAF) under ASTM D7566-24a.

Processes and systems for production of sustainable aviation fuel from syngas via mixed alcohols

Higher mixed alcohols are produced from syngas contacting a catalyst in a reactor. The catalyst has a first component of molybdenum or tungsten, a second component of vanadium, a third component of iron, cobalt, nickel or palladium and optionally a fourth component of a promoter. The first component forms alcohols, while the vanadium and the third component stimulates carbon chain growth to produce higher alcohols.
