Abstract: A method is disclosed for preparing a renewable fuel blend. The method includes subjecting at least two feedstocks of different biological origins to catalytic cracking in a catalytic cracking unit and to hydrotreatment in a hydrotreatment unit to form a fuel blend having an aromatic hydrocarbon content from 26 to 42 wt-% and a paraffinic hydrocarbon content of less than 53 wt-%, as measured according to ASTM D2425-04 (2011). The fuel blend is formed by mixing the at least two feedstocks together before subjecting them to the catalytic cracking and hydrotreatment, or by obtaining a first fuel component and at least one further fuel component from the catalytic cracking and hydrotreatment of the at least two feedstocks, and mixing the first fuel component and the at least one further fuel component together.

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.
