This work demonstrated that bio-jet fuels can be directionally prepared from bagasse (a typical lignocellulose biomass) by integrating bio- and chemical catalysis reaction processes. This controllable transformation started with the preparation of acetone/butanol/ethanol (ABE) intermediates through the enzymolysis and fermentation of bagasse. Pretreatment of bagasse by deep eutectic solvent (DES) promoted the enzymatic hydrolysis and fermentation because it destroyed the structure of biomass and remove lignin in lignocellulose. Subsequently, the selective catalytic conversion of sugarcane derived ABE broth to jet range fuels was achieved through an integrated process: ABE dehydration to light olefins over the HSAPO-34 catalyst and olefin polymerization to bio-jet fuels over the Ni/HBET catalyst. The dual catalyst bed synthesis mode improved the selectively of bio-jet fuels. High selectivity of jet range fuels (83.0 %) and high conversion of ABE (95.3 %) were obtained by the integrated process. Copyright © 2023 Elsevier Ltd. All rights reserved.
