Co-conversion of lignocellulosic derivatives to jet fuel blending by an efficient hydrophobic acid resin

Bio-jet fuel synthesis is a promising way to upgrade the value of lignocellulose and contributes to the sustainable development. Presently the property of bio-jet fuel is weakened by single component produced using pure feedstock and water produced in the reaction leading to acid leaching. Therefore, we synthesized a hydrophobic acid resin (R-x) and used it to catalyze lignocellulose-derived mixture upgrading to high-performance bio-jet fuel blending, where R-x shows better activity than Amberlyst-15, Nafion-212 and Hβ with 75.4% of product yield obtained in co-conversion of lignocellulosic derivatives. The better activity of R-x is ascribed to the strong acid, big acid concentration, large surface area and especially super hydrophobicity resulting as R-x recycled steadily in consecutive 5 runs. After hydrodeoxygenation, jet fuel blending with high density and excellent freezing point better than JP-7 was obtained. This work demonstrates an efficient catalyzing method to synthesize high-performance jet fuel by co-conversion of lignocellulosic derivatives.
