Heterogeneous zeolite/zeotype catalysts are attractive for converting renewable biomass-derived chemicals into transportation fuels by aldol condensation reactions, which provide a simple strategy to improve carbon numbers. Herein, Zr-doped aluminum phosphate (ZrAPO-5) were applied for efficient syntheses of diesel and jet fuel range C11, C12 and C16 intermediates from biomass-derived furfural (FF) and cyclohexanone (CH).
Incorporation of Zr in the APO-5 framework facilitated the adsorption of the C=O groups of FF and CH and created more and stronger acid and base sites, which co-catalyzed the aldol condensation and facilitated the product yields. ZrAPO-5 (Zr/Al = 0.20) yielded up to 79.3% single aldol condensation product C11 or 80.7% double aldol condensation product C16 in the cross-aldol condensation of FF and CH under appropriate reaction conditions, and also realized 83.3% C12 yield in the self-aldol condensation of CH.
In addition, the catalytic system displayed good to excellent yields of other value-added chemicals in aldol condensations of alternative carbonyl compounds.
