The hydrodeoxygenation of bioderived furans into alkanes

Nature Chemistry, 2013
The 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

Recent advances in the selective catalytic hydrodeoxygenation of lignin-derived oxygenates to arenes

, 2020
The utilization of lignin-derived compounds is an important part of biomass valorization. One promising way to achieve this goal is to reduce/eliminate the oxygen content via hydrodeoxygenation (HDO), producing valuable fuels and chemicals. However, most

Ni/hierarchical ZSM-5 zeolites as promising systems for phenolic bio-oil upgrading: Guaiacol hydrodeoxygenation

, 2020
Hierarchical ZSM-5 with mesopores were derived from seed directing crystalline process. The efficient encapsulation of nickel metal was achieved by a simple incipient wetness impregnation method, and a stable Ni/hierarchical ZSM-5 hydrodeoxygenation (HDO)

Influence of sulphur level on hydrodeoxygenation

Applied Catalysis, 1989
The 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.

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.

Relationship between Atomic Scale Structure and Reactivity of Pt Catalysts: Hydrodeoxygenation of m-Cresol over Isolated Pt Cations and Clusters

, 2020
Atomically dispersed late transition-metal cations have attracted significant attention as next-generation heterogenous catalysts. However, relationships between the catalytic behavior of atomically dispersed metal cations and active sites on metal ...
