TL;DR: A wheat straw soda lignin was characterized and converted into gases and liquids under H2 pressure, at 350°C over a supported NiMo sulfide catalyst, using tetralin as a hydrogen-donor solvent in a batch autoclave as discussed by the authors.

TL;DR: The main thermochemical ways such as pyrolysis, solvolysis, hydrothermal conversion and hydroconversion considered for the valorization of the lignin are reviewed in this article.

TL;DR: In this article, a process for direct hydroliquefaction of biomass selected from algae, lignocellulosic biomass and/or of one or more constituents of lignin for producing fuel bases comprising two successive hydroconversion stages under high hydrogen pressure in ebullating bed reactors is described.

TL;DR: Complete two-dimensional gas chromatography has been investigated to provide enhanced molecular characterization of oxygen-containing species in coal-derived liquids and it can be concluded that a non-orthogonal arrangement involving a highly polar column in the first dimension was the most adapted one.

TL;DR: Comprehensive on-line two-dimensional liquid chromatography was used for the characterization of bio-oils obtained by fast pyrolysis of lignocellulosic biomass, and the best of both techniques was applied to the separation of the aqueous phase of a partially dehydroxygenated bio-oil.
