Conversion of furfuryl alcohol to alkyl levulinate fuel additives over Al₂O₃/SBA-15 catalyst

Abstract

Al2O3/SBA-15 catalyst is effective in the alcoholysis of furfuryl alcohol to alkyl levulinates in both batch and continuous processes at atmospheric pressure.

Low-cost synthesis of nanoaggregate SAPO-34 and its application in the catalytic alcoholysis of furfuryl alcohol

“…This shows that, during the first hour, the conversion of FAL is over 99% and the main products are EMF (43%) and EL (36%), with a small amount of DEP (7%). With a prolonged reaction time, the amount of EMF decreased gradually and that of EL correspondingly increased, indicating that EMF is the key intermediate in the FAL alcoholysis reaction, which is in agreement with previous reports [45,46]. Notably, although complete conversion of FAL can be achieved within 1 h, the maximum EL yield is achieved after 6 h, with the decrease in the EMF yield.…”

Ni/KIT-6 catalysts for hydrogenolysis of lignin-derived diphenyl ether

“…The application of mesoporous silica as support offers high surface area, uniform pore channels to accommodate active species, hydrophobic nature and high thermal stability. 16,17 Here in we report hydrogenolysis of DPE over Ni/KIT-6 catalysts in continuous process at atmospheric H 2 .…”

Advances in Nanocatalyst Design for Biofuel Production

“…In particular,a lkyl levulinates can be produced from lignocellulosicf eedstocks (C5 sugars) and have been reported to be produced fromf urfuryl alcohol using alumina/SBA-15 heterogeneous catalysts. [117] A2 0wt% Al 2 O 3 /SBA-15 catalyst exhibited the best activity in the alcoholysis of furfuryl alcohol with n-butanol, giving 94 % selectivity toward n-butyl levulinate in abatch process, with results also transferable to acontinuous flow process.…”
