Hydrodeoxygenation of dibenzofuran and related compounds

AIChE Journal, 1981
AbstractThe catalytic hydrodeoxygenation (HDO) of dibenzofuran was examined on a presulfided NiMo/γAl2O3 catalyst. Based on the reaction intermediates identified in the present study a reaction network for the removal of oxygen from dibenzofuran has been established.

Hydrodeoxygenation of pyrolysis oil in a microreactor

Chemical Engineering Science, 2012
Abstract Use of a packed bed microreactor for the first stage hydrodeoxygenation (HDO) of pyrolysis oil was investigated. The effects of various processing conditions such as temperature, hydrogen partial pressure, and residence time on Extent of HDO, hydrogen consumption, and space-time-consumption were investigated using reduced sulfided NiMo/Al 2 ...

Hydrodeoxygenation of benzophenone on Pd catalysts

Applied Catalysis A: General, 2005
Abstract Catalytic hydrogenation and hydrogenolysis of benzophenone in a liquid phase at the reaction temperature of 130 °C and pressure 6 MPa on supported palladium catalysts were investigated. A number of different supports including active carbon, alumina, Beta and ZSM-5 zeolites with different Si/Al ratios and MCM-41 was tested.

Nickel catalysts for the hydrodeoxygenation of biodiesel

Kinetics and Catalysis, 2010
A number of nickel and nickel-copper catalysts for the hydrodeoxygenation of fatty acid esters (biodiesel) were studied. The CeO2 and ZrO2 oxides and the CeO2-ZrO2 binary system were used as supports. The Ni-Cu/CeO2-ZrO2 catalyst exhibited the highest activity; it allowed us to quantitatively convert biodiesel into linear alkanes under mild conditions (

Hydrodeoxygenation of Anisole with Pt Catalysts

Industrial & Engineering Chemistry Research, 2017
Pt catalysts supported on neutral and acid materials, namely SiO2, γ-Al2O3, Na-Beta, and NaH-Beta, were studied in the anisole deoxygenation reaction. The main objective was to compare different supports for this reaction and determine the conditions that maximize the selectivity to deoxygenated products.

The mechanism of catalytic hydrodeoxygenation of furan

Applied Catalysis, 1983
Abstract The distribution and yield of products from the hydrodeoxygenation of furan over cobalt molybdate catalyst were measured. Presulfiding resulted in a marked increase in the yield compared to the yield obtained over a reduced catalyst. Under similar conditions tetrahydrofuran was about three times more reactive than furan.

Thermodynamics and the hydrodeoxygenation of 2,3-benzofuran

1990
Ideal-gas thermodynamic properties for 2,3-benzofuran and 4,5-dihydro-2,3-benzofuran based on accurate calorimetric measurements were determined. Critical-temperature/density measurements obtained using a differential scanning calorimeter (DSC) are reported for 2,3- benzofuran.

Depolymerization and Hydrodeoxygenation of Switchgrass Lignin with Formic Acid

ChemSusChem, 2012
AbstractOrganosolv switchgrass lignin is depolymerized and hydrodeoxygenated with a formic acid hydrogen source, 20 wt % Pt/C catalyst, and ethanol solvent. The combination of formic acid and Pt/C is found to promote production of higher fractions of lower molecular weight compounds in the liquid products.

Modeling of oxolane hydrodeoxygenation in the presence of tungsten disulfide

Журнал структурной химии, 2018
A theoretical study of hydrotreatment of the oxolane molecule without a catalyst and in the presence of a catalyst is performed by numerical DFT/B3LYP methods with 6-31G(d) and LanL2DZ basis sets. The catalyst used in this study is tungsten disulfide (WS2) which is mo­deled by a three anionic vacancy site WS3H3+.

Catalytic hydrodeoxygenation III. Interactions between catalytic hydrodeoxygenation of m-cresol and hydrodenitrogenation of indole

Journal of Catalysis, 1983
Abstract Simultaneous hydrodenitrogenation (HDN) and hydrodeoxygenation (HDO) is studied with indole/ m -cresol conversions over a sulfided CoMo HDS catalyst. The mutual inhibition of indole (and indoline) on HDO and of m -cresol on HDN is established.
