The performance of Pd catalysts supported on SiO2, Al2O3 and ZrO2 for the hydrodeoxygenation (HDO) phenol has been compared in gas phase, at 300 °C 1 atm using a fixed bed reactor. While SiO2 exhibits high selectivity to cyclohexanone, when an oxophilic support such as ZrO2, it favors toward benzene, reducing formation ring-hydrogenated products, cyclohexanone cyclohexanol. Diffuse reflectance infrared Fourier transform spectroscopy experiments participation keto-tautomer intermediate...
This work investigates the effect of type support (SiO2, Al2O3, TiO2, ZrO2, CeO2, and CeZrO2) on performance Pd-based catalysts for hydrodeoxygenation phenol at 573 K using a fixed-bed reactor. Product distribution is significantly affected by support. Benzene was major product over Pd/TiO2 Pd/ZrO2; other hand, cyclohexanone main compound Pd/SiO2, Pd/Al2O3, Pd/CeO2, Pd/CeZrO2. A reaction mechanism based tautomerization proposed basis DRIFTS experiments catalytic tests with intermediate...
This work studies the effect of zirconia structure on performance Pd/ZrO2 catalysts for hydrodeoxygenation phenol at 300 °C and 1 atm using a fixed bed reactor. Benzene was major product over Pd/t-ZrO2, while significant formation cyclohexanone observed Pd/m-ZrO2. On other hand, Pd/m,t-ZrO2 exhibited intermediary behavior. DRIFTS adsorbed pyridine, NH3-TPD, dehydration cyclohexanol reaction revealed that Pd/t-ZrO2 catalyst exhibits higher density oxophilic sites than Pd/m-ZrO2 Pd/m,t-ZrO2....
Mono and bimetallic catalysts based on Pt Pd were prepared by a co-precipitation method. They tested in liquid phase hydrogenation reactions of glucose furfural at low temperature pressure. The PtPd/TiO2 catalyst proved to be an efficient material selectively hydrogenating sorbitol. Moreover, high conversion was attained under relatively soft conditions, the furfuryl alcohol selectivity strongly affected chemical composition catalysts. Furfuryl (FA) major product most cases, along with side...
To screen 20 micro-organisms for ω-transaminase (ω-TA) activity by the kinetic resolution of rac-1-phenylethylamine, followed testing rac-amines pharmaceutical interest with bulky substituents and to conduct asymmetric synthesis a chiral amine.Stemphylium lycopersici was selected as best biocatalyst. By central composite rotatable design (CCRD), it found that, at lower pH (5·5 6·5), lyophilized micro-organism biocatalysed rac-1-phenylethylamine 99% enantiomeric excess (e.e.) ((R)-enantiomer)...
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).
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...
