Disclosed herein are embodiments of a method for making jet fuel blendstocks that comprise partially hydrogenated carbocyclic compounds and which can be used to replace aromatic-containing fuels and that exhibit suitable seal swell properties. The disclosed method embodiments utilize catalysts and reaction conditions that facilitate partially hydrogenating carbocyclic compounds present in mixtures obtained from renewable sources, such as bio-based fermentation products. The reaction product mixtures obtained from the disclosed method can be blended with blendstocks to provide fuels that avoid soot formation caused by aromatic-containing fuels and that exhibit seal swelling that meet requirements in aviation systems.

Method embodiments for partial hydrogenation of carbocyclic compounds to produce jet fuel blendstock

A method for forming a desired hydrocarbon fuel product from a mixed oxygenate feedstock by utilizing chemical processes to form ketones from the oxygenate feed, upgrade the ketones, recycle selected upgraded ketones through the upgrading process to obtain a desired intermediate and hydrogenating the desired intermediate to obtain the desired hydrocarbon fuel product. In various alternative configurations and embodiments this can be accomplished in a number of ways, and originate in a number of different positions and occasions.
