Selective hydrodeoxygenation of lignin-derived phenols to aromatics catalyzed by Nb2O5-supported iridium

, 2022
Here we report the first heterogeneous iridium-based catalyst (Ir@Nb2O5) able to combine full conversion in hydrodeoxygenation (HDO) of lignin-derived phenols to hydrocarbons with appreciable selectivity for aromatics.

Hydrodeoxygenation of Guaiacol Over Orthorhombic Molybdenum Carbide: A DFT and Microkinetic Study

, 2021
The hydrodeoxygenation of guaiacol is modelled over a (100) β-Mo2C surface using density functional theory and microkinetic simulations. The thermochemistry of the process shows that the demethoxylation of the guaiacol, to form phenol, will be the ...

Temperature Dependence of Single Step Hydrodeoxygenation of Liquid Phase Pyrolysis Oil

Frontiers in Chemistry, 2018
In this paper, continuous hydrodeoxygenation (HDO) of liquid phase pyrolysis (LPP) oil in lab-scale is discussed. Pyrolysis oil is derived from the bioCRACK pilot plant from BDI - BioEnergy International GmbH at the OMV refinery in Vienna/Schwechat ...

Process Simulation Modelling of the Catalytic Hydrodeoxygenation of 4-Propylguaiacol in Microreactors

Fuels, 2021
A process simulation model was created using Aspen Plus to investigate the hydrodeoxygenation of 4-propylguaiacol, a model component in lignin-derived pyrolysis oil, over a presulphided NiMo/Al2O3 solid catalyst. Process simulation modelling methods were

Hydrodeoxygenation and hydrodenitrogenation of n-hexadecanamide over Pt catalysts: effect of the support

, 2023
Efficient catalysts for simultaneous hydrodeoxygenation (HDO) and hydrodenitrogenation (HDN) are needed for the production of renewable fuels. In this study, Pt catalysts supported on SiO2, ɣ-Al2O3, SiO2-Al2O3, ZrO2, CeO2-ZrO2, Nb2O5, and TiO2 were ...

Synthesis of Renewable High-Density Fuel with Vanillin and Cyclopentanone Derived from Hemicellulose

Molecules, 2023
1,3-bis(cyclohexylmethyl)cyclopentane, a renewable high-density fuel, was first produced in a high overall carbon yield (79.5%) with vanillin and cyclopentanone, which can be derived from biomass. The synthetic route used in this work contains two steps.
