Abstract
Bio-aviation fuels were prepared by the catalytic upgrading of lignocellulose fast pyrolysis oil, or bio-crude. Hydrotreating was performed for upgrading the oils. The oxygen atoms in the bio-crude were removed using the fixed bed continuous flow reaction systems composed of the multiple catalyst beds. The complete deoxygenation was observed and the possible applications of bio-crude-derived deoxygenated hydrocarbon fuels for aviation fuels were discussed. The detailed characterizations of catalysts using Raman, XRD, XPS, TEM, and other methods confirmed the improved activity or selectivity of the catalysts used in this study. The reaction products were also analyzed using GC, GPC, Karl Fischer titration, and other methods for understanding the reaction pathways and for obtaining the insight to improve the upgrading process.
