摘要: Nowadays, the utilization of renewable biomass as a substitute for petroleum-based feedstock in the synthesis of aerospace fuel has garnered significant attention. In this work, we use molecular sieve to catalyze the controllable oligomerization of lignocellulose platform molecule furfuryl alcohol, which is prone to polymerize and generate furfuryl alcohol resin and other macromolecular substances. In order to reduce the formation of macromolecule polymers and enhance the yield of oligomers within the C9-C15 range, the reactive extraction strategy was implemented. Utilizing a low polar solvent, increasing the extraction phase content, employing a hydrophilic and weakly acidic molecular sieve are all beneficial for enhancing the yield of the target products. Finally, under the optimal conditions, the conversion of furfuryl alcohol reaches 84.7% and the yield of the target products is improved from 10%-15% to 41.4%. After hydrodeoxygenation, a liquid fuel with paraffin as the main component was obtained. Moreover, the effect of substituents on the polymerization activity of furan derivatives was compared, the alkyl side chains as substituents can enhance both reactant activity and yield of target products. This study presents a viable approach for the efficient synthesis of aviation fuel directly from bio-based furfuryl alcohol.
