Abstract: Provided is a method for upgrading polymer waste-based material. The method includes providing a polymer waste-based feedstock, providing a crude oil-derived feedstock, blending the polymer waste-based feedstock, the crude oil-derived feedstock, and optionally a further feed material, to provide a feed mixture, hydrotreating the feed mixture at hydrodesulphurisation conditions to provide a hydrotreated material boiling in the middle distillate range, and recovering at least a jet fuel component from the hydrotreated material.

Abstract: The present disclosure relates to methods for preparing aviation fuel component from a feedstock containing fossil hydrotreating feed and a second feed containing esters of fatty acids and rosins, free fatty acids and resin acids. The method includes subjecting the feedstock to hydrotreatment reaction conditions to produce a hydrotreated stream, separating the hydrotreated stream to three fractions from which at least part the highest boiling fraction is subjected to hydrocracking reaction to produce a hydrocracked stream. At least part of the hydrocracked stream is admixed with at least part of the hydrotreated stream, and their admixture is processed further until desired conversion of the feedstock to the aviation fuel component is obtained.
