“…With respect to biomassvalorization,aldol condensation of furfural anda cetone has been studied in detail, as after hydrogenation the reaction products have characteristics of high quality diesel fuel components. [31,32] Furthermore, some biomass-derived compounds,s uch as terpenes, have cyclic aliphatic rings and can be directly used as high-density biofuel additives. [9][10][11][15][16][17] In contrast, the selective depolymerization of lignin results in av ariety of phenolic and aromatic molecules whosecyclic structure can provide the necessary characteristics of potentiala viation fuels produced from biomass.T oa rrive at aviation fuel components, lignin-derivedc ompounds should be processed by one of the following strategies:1 )aldol condensation of short-chain aldehydes with (substituted) cyclic ketones [18][19][20][21] obtained by partial hydrogenation of phenolics from lignin [22,23] or furanics [24][25][26] ,o r2 )self-condensation of cyclic ketones, [27][28][29][30] or 3) alkylation of lignin-derived aromatics by short chain alcohols.…”

This study presents results on aldol condensation of furfural and cyclohexanone in presence of Mg‐Al hydrotalcite‐derived materials as solid basic catalysts at reaction temperatures from 25 to 90 °C and a cyclohexanone to furfural molar ratio of 1–10. Mg‐Al mixed oxide exhibited reasonable activity with furfural conversion of ca. 50 % after 180 min of the reaction at T=90 °C. The activity of reconstructed hydrotalcite was much higher with furfural conversion close to 100 % at short reaction times. In comparison with Mg‐Al mixed oxide, the initial reaction rate has increased 30–50 times. Under similar reaction conditions, cyclohexanone self‐condensation on HTC‐derived catalysts could not compete with aldol condensation because the former reaction was inhibited by produced water. The change in CH/F molar ratio influenced both furfural conversion and product selectivity; higher furfural content in the reaction mixture favored the second condensation step.

Diesel or jet fuel range C 10 -C 17 branched and cyclic alkanes were produced by reaction of 3-pentanone derived from lactic acid with bio-based aldehydes through aldol condensation followed by hydrodeoxygenation. DBU (1,8-diazabicycloundec-7-ene) was identified as an efficient catalyst for the aldol reaction of 3-pentanone with furan based aldehydes, and the selectivity of single or double aldol condensation product could be easily controlled by adjusting the reaction temperature. For the reaction with aromatic aldehydes, aluminium phosphate demonstrated a higher catalytic activity than DBU and mechanisms were proposed for the difference in the catalytic activity. The final hydrodeoxygenation step could be achieved by using a simple Pd/C + H-beta zeolite system, excellent selectivity was observed under the present system, the clean formation of hydrocarbons with a narrow distribution of alkanes occurred in most cases.Scheme 1 (a) Previous work versus (b) our new protocol for the synthesis of liquid alkanes using 3-pentanone as a bio-based synthon.This journal is

“…Other promising pathways such as hydrotreating of vegetable oils and Fischer Tropsch synthesis have been intensively investigated with the aim of producing bio-jet fuels [5]. Although these technologies show promising potential in the manufacture of jet fuel range alkanes, the synthetic feedstocks extracted from plant or animal oils are commonly upgraded under high hydrogen pressure in the presence of noble metals catalysts or sulfide-based catalysts [14].…”

“…Nonetheless, two main compositions of cyclic paraffins and aromatics in commercial military jet fuels are hard to attain from well-developed hydrotreating of vegetables or Fischer-Tropsch synthesis [14]. On the other hand, it is widely known that oxygen content of bio-oil can be partially or even completely eliminated by zeolite cracking during fast pyrolysis of biomass [29].…”
