Abstract Bio‐oil obtained from the depolymerization of lignocellulosic biomass is a potential alternative source to replace fossil fuels. However, due high oxygen content, bio‐oil must be upgraded. In this direction, hydrodeoxygenation reaction (HDO) widely applied. Considering complex chemical composition bio‐oil, variety model molecules have been used in literature study mechanism HDO process. work, we discuss heterogeneous catalysts and conditions (temperature, pressure, solvent)...
Materials exhibiting different textural and surface properties (SiO 2 , TiO ZrO ZSM-5) were investigated as supports for Mo carbides in the upgrading of furfural (FF) liquid phase to produce 2-methylfuran (2MF).
The effect of metal and support acidity on the hydroconversion dimeric aryl ethers, used as model molecules for lignin, is still under debate, both in terms hydrogenolysis (cleavage ether bond) formation by-products (coupling aromatic monomers to dimers by alkylation reaction). Their role investigated here conversion three typical representative α-O-4, β-O-4, 4-O-5 linkages respectively, benzyl phenyl (BPE), phenethoxybenzene (PEB), diphenyl (DPE), at 503 K, 18 bar H2 decalin. Ru- Pd-based...
This work investigates the role of support and metal particle size in performance Pd-based catalysts for hydroconversion benzyl phenyl ether (BPE) liquid phase. supported on different oxides (SiO2, TiO2, Nb2O5, Al2O3, ZrO2, HZSM5) were synthesized by incipient wetness impregnation (particle > 4 nm) sol-immobilization methods < nm). Different reaction pathways leading to aromatics, polyaromatics, or cycloalkanes have been evidenced, acidity competition between these has clarified. The acid...
Abstract The hydrodeoxygenation of furfural (FF) over Mo carbides in liquid phase at 200 °C, 30 bar H 2 for 4 h 2‐butanol was investigated. Unsupported and SiO ‐supported carbide with different crystallographic phases (β‐Mo C/SiO α‐MoC/SiO ), the presence Cu Ni as promoters were studied. reactivation treatment under atmosphere passivated investigated by XAS. results show that is present states oxidation catalysts, more severe bimetallic systems, which original are not restored after...
