Components for bio-jet fuel production can be achieved by catalytic cracking of fatty oils and fatty acids over activated carbon catalyst. At reaction temperatures of about 450 °C, mainly C15- and C16-n-Alkanes that can be isomerized for jet fuel-usage are produced. They can be used for bio-kerosene after isomerization. Introducing high-oleic feedstock like HO-sunflower-oil and slightly raising the reaction temperature leads to high amounts of n-alkanes in the jet-fuel boiling range. The process proves to be very robust concerning feedstock compositions and impurities. Therefore, catalytic cracking over activated carbon is an ideal pathway to transform not only bio-based oils, but also their wastes and fatty acid-containing by-products from plant oil processing into high-quality fuel components. Using alternative catalysts leads to an enhanced production of alkylated benzenes which are indispensable for aviation jet fuel.
