Processing renewable resources to produce renewable fuels

A process for producing a sustainable aviation fuel, comprising:

• coprocessing a liquid biomass effluent having a first aromatic content of greater than or equal to about 10 vol. % by subjecting the liquid biomass effluent to a hydrodeoxygenation catalyst and under hydrodeoxygenation reaction conditions, thereby producing a hydrodeoxygenated liquid effluent, and subjecting the hydrodeoxygenated liquid effluent to a first hydroisomerization catalyst and under first hydroisomerization reaction conditions, thereby producing a hydroisomerized liquid effluent having a second aromatic content less than the first aromatic content;
• coprocessing a liquid feedstock comprising one or more of fats, oils and greases in the presence of a hydrotreating catalyst and under hydrotreating conditions, thereby producing a liquid hydrotreating effluent having a first n-paraffin content greater than or equal to about 60 vol. %, and subjecting the liquid hydrotreating effluent to a second hydroisomerization catalyst and under second hydroisomerization reaction conditions, thereby producing a liquid hydrocarbon product having a second n-paraffin content less than about 40 vol. % and a third aromatic content of less than about 1 vol. %;
• fractioning the liquid hydrocarbon product to obtain individual fractions, wherein a given individual fraction is a first sustainable aviation fuel having the second n-paraffin content and the third aromatic content;
• and
• combining the hydroisomerized liquid effluent with the first sustainable aviation fuel to produce a second sustainable aviation fuel having a third n-paraffin content less than about 25 vol. % and a fourth aromatic content of at least 8 vol. %.
