The role of acid and metal sites in hydrodeoxygenation of guaiacol over Ni/Beta catalysts

, 2020
Hydrodeoxygenation (HDO) of guaiacol over Ni metal supported on zeolites (H-Beta and H-ZSM-5) with different Si/Al ratios (12.5, 25, 175) and different metal loadings (2.3–23.4 wt%) was investigated in order to elucidate the role of catalyst acidity and ...

Guaiacol hydrodeoxygenation over Ni2P supported on 2D-zeolites

, 2020
Different 2D zeolites, namely lamellar ZSM-5 (L-ZSM-5), the corresponding silica pillared ZSM-5 (PI-ZSM-5) and an MCM-22 sample, were investigated as nickel phosphide supports and evaluated as catalysts for guaiacol hydrodeoxygenation (HDO ...

Synergistic effect of Ni-Co alloying on hydrodeoxygenation of guaiacol over Ni-Co/Al2O3 catalysts

, 2020
The hydrodeoxygenation (HDO) of guaiacol was investigated in a batch reactor using Ni-Co/γ-Al2O3 catalysts prepared by co-impregnation method. The structural and physicochemical properties of the catalysts were investigated using BET, XRD, H2-TPR, FT-IR,

Production of antimicrobial powders of guaiacol oligomers by a laccase-catalyzed synthesis reaction

Process Biochemistry, 2021
Guaiacol oligomers were synthesized by enzyme-catalyzed polymerization with laccase as the catalyst. The polymerization procedure in aqueous media was followed by UV-Vis spectra. The oligomers were characterized by NMR and MALDI-TOF spectra.

Spray pyrolysis synthesis of bimetallic NiMo/Al2O3–TiO2 catalyst for hydrodeoxygenation of guaiacol: Effects of bimetallic composition and reduction temperature

, 2020
Catalytic hydrodeoxygenation (HDO) is a process for removing of oxygen from oxygen-containing compounds using a catalyst. In this study, spherical bimetallic NiMo/Al2O3–TiO2 catalysts with different Ni/Mo ratios were successfully synthesized by combining

Flexible NiCo-based catalyst for direct hydrodeoxygenation of guaiacol to cyclohexanol

, 2020
The catalytic hydrodeoxygenation (HDO) of lignin-derived phenols is an important step for bio-oil upgrading. Herein, a novel HDO system was established in the presence of nitrogen, instead of traditional hydrogen.
