Hydrodeoxygenation of Guaiacol over Ceria–Zirconia Catalysts
ChemSusChem, 2015AbstractThe hydrodeoxygenation of guaiacol is investigated over bulk ceria and ceria–zirconia catalysts with different elemental compositions. The reactions are performed in a flow reactor at 1 atm and 275–400 °C. The primary products are phenol and catechol, whereas cresol and benzene are formed as secondary products.

The hydrodeoxygenation of bioderived furans into alkanes
Nature Chemistry, 2013The conversion of biomass into fuels and chemical feedstocks is one part of a drive to reduce the world's dependence on crude oil. For transportation fuels in particular, wholesale replacement of a fuel is logistically problematic, not least because of the infrastructure that is already in place. Here, we describe the catalytic defunctionalization of a

Hydrodeoxygenation of Pyrolysis Oils
Energy Technology, 2016AbstractThe hydrodeoxygenation (HDO) of bio‐oil derived from white oak wood using non‐sulfided catalysts was studied in a two zone continuous flow trickle bed reactor system. The major organic components of the pyrolysis oil were pyrolytic lignin (large phenolic polymers), xylose, levoglucosan, organic acids (primarily acetic acid), and ...

N2-promoted hydrodeoxygenation
Nature Catalysis, 2019Because of the high strength of N≡N bonds, N2 is often employed as an inert gas. Now it has been shown that it can partly react to yield surface nitrogen species that facilitate C–O hydrogenolysis reactions on supported Ru catalysts.

Influence of sulphur level on hydrodeoxygenation
Applied Catalysis, 1989The effect of catalyst sulphidation on hydrodeoxygenation was studied under pseudo-steady-state conditions in a continuous trickle-bed reactor at 523 K. Sulphur was added to the feed in the form of carbon disulphide. The catalyst used was a commercial CoO-MoO3/γ-Al2O3 hydrotreating catalyst which was presulphided at 523 or 623 K.

Hydrodeoxygenation of acetic acid in a microreactor
Chemical Engineering Science, 2012Abstract Acetic acid was used as a model compound for pyrolysis oil in a hydrodeoxygenation (HDO) study. HDO of acetic acid was performed in a packed bed microreactor. The catalyst was reduced sulfided NiMo/Al2O3. The effects of state of aggregation of acetic acid, temperature, hydrogen partial pressure, liquid flow rate, reactor diameter, and ...

Chemistry of Catalytic Hydrodeoxygenation
Catalysis Reviews, 1983Abstract Hydrodeoxygenation (HDO) reactions occur simultaneously with hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) during catalytic hydrotreatment of liquid fuels. Extensive research activities in the areas of HDS and HDN have been dictated by environmental concern to limit SO2 and NOX emissions.

Hydrodeoxygenation of Triglycerides into Renewable Diesel
Triglycerides or vegetable oils as fuels is an old idea that can be traced back to the early days of diesel engine development. In this chapter, an overview of the fuel properties of triglycerides and their various upgrading technologies (physical and chemical; catalytic or non-catalytic) are discussed.Ajaikumar Samikannu +5 more

Hydrodeoxygenation of a Lignin Model Compound
1988With the goal of developing a process for producing high octane gasoline blending compounds from lignin, a series of Mo and NiMo catalysts on aluminophosphate supports, having P:A1 atomic ratios of 0 to 1, have been screened for their ability to hydrodeoxygenate and dealkylate a lignin model compound, 4-propylguaiacol. Their performance was compared to
