Method for production of low-carbon aviation fuel through reactive viscosity control

Abstract

Provided is a process for producing sustainable aviation fuel (SAF) from a renewable feedstock, for example fats, oils, and greases (FOG). The process comprises hydroprocessing paraffins using a Linde Type A (LTA) zeolite to selectively hydrocrack scantily branched isoparaffins. Hydroisomerization when using the present LTA catalysts greatly improves carbon efficiency because it maximizes the SAF yield and minimizes hydrogen losses to the manufacture of undesirable (lower boiling) products. By minimizing the SAF fraction that needs to be relegated to renewable diesel through selective hydrocracking of the molecules with the highest viscosity, the carbon efficiency of the reaction is greatly improved.
