Role of transition metals on MoS 2 -based supported catalysts for hydrodeoxygenation (HDO) of propylguaiacol
You Wayne Cheah,Muhammad Abdus Salam,Prakhar Arora,Olov G.W. Öhrman,Derek Creaser,Louise Olsson +5 more
TL;DR: In this paper, MoS2/γ-Al2O3 promoted by transition metals like nickel (Ni), copper (Cu), zinc (Zn), and iron (Fe) was evaluated for catalytic hydrodeoxygenation (HDO) of a bio-oil model compound, 4-propylguaiacol (PG) in a batch reactor at 340 °C under 50 bar H2 pressure.

Comparative study of the solvolytic deconstruction of corn stover lignin in batch and flow-through reactors
TL;DR: In this article, the authors demonstrate that it is possible to overcome the limitations inherent to batch reactors by carrying out the solvolytic deconstruction in flow-through reactor systems as they allow for the continuous removal and rapid cooling of the products.

A review of catalytic upgrading of bio-oil to engine fuels
Peter Mølgaard Mortensen,Jan-Dierk Grunwaldt,Peter Arendt Jensen,K.G. Knudsen,Anker Degn Jensen +4 more
TL;DR: In this article, two general routes for bio-oil upgrading have been considered: hydrodeoxygenation (HDO) and zeolite cracking, where zeolites, e.g. HZSM-5, are used as catalysts for the deoxygenization reaction.

Chemical modification of lignins: Towards biobased polymers
TL;DR: Lignin is a highly abundant biopolymeric material that constitutes with cellulose one of the major components in structural cell walls of higher vascular plants and is used as a precursor for the elaboration of original macromolecular architecture and the development of new building blocks as mentioned in this paper.
