“…23,24,66,71,321,323 The class of lignin-derived alkanes, and more specifically C 1-3 -alkylated cyclohexanes, includes interesting candidates to serve as mid-range fuel additives. 593 It has been demonstrated numerous times that cyclohexanes can be acquired in high yields from methoxylated phenols through the combined action of both metal catalysis (hydrogenation) and Brønsted acidity (dehydration and/or demethoxylation). 244,[594][595][596][597][598][599][600][601][602][603][604] Noble metals (Ru, Rh, Pd, Pt) have been shown to provide excellent hydrogenation activity in these transformations, but also cheaper Ni-based catalyst have been applied successfully.…”

In pursuit of more sustainable and competitive biorefineries, the effective valorisation of lignin is key. An alluring opportunity is the exploitation of lignin as a resource for chemicals. Three technological biorefinery aspects will determine the realisation of a successful lignin-to-chemicals valorisation chain, namely (i) lignocellulose fractionation, (ii) lignin depolymerisation, and (iii) upgrading towards targeted chemicals. This review provides a summary and perspective of the extensive research that has been devoted to each of these three interconnected biorefinery aspects, ranging from industrially well-established techniques to the latest cutting edge innovations. To navigate the reader through the overwhelming collection of literature on each topic, distinct strategies/topics were delineated and summarised in comprehensive overview figures. Upon closer inspection, conceptual principles arise that rationalise the success of certain methodologies, and more importantly, can guide future research to further expand the portfolio of promising technologies. When targeting chemicals, a key objective during the fractionation and depolymerisation stage is to minimise lignin condensation (i.e. formation of resistive carbon-carbon linkages). During fractionation, this can be achieved by either (i) preserving the (native) lignin structure or (ii) by tolerating depolymerisation of the lignin polymer but preventing condensation through chemical quenching or physical removal of reactive intermediates. The latter strategy is also commonly applied in the lignin depolymerisation stage, while an alternative approach is to augment the relative rate of depolymerisation vs. condensation by enhancing the reactivity of the lignin structure towards depolymerisation. Finally, because depolymerised lignins often consist of a complex mixture of various compounds, upgrading of the raw product mixture through convergent transformations embodies a promising approach to decrease the complexity. This particular upgrading approach is termed funneling, and includes both chemocatalytic and biological strategies.

“…The deoxygenation process is a prospective alternative to transesterification allowing diesel‐range hydrocarbons to be produced from a wide range of feedstocks. The composition of the deoxygenation products, which consist of linear and branched, saturated and unsaturated C 13 –C 23 hydrocarbons, depends on the composition of the raw material, the catalyst, and the process conditions . As natural triglycerides mainly include the acyls with an even number of carbon atoms, the major products are n ‐tridecane, n ‐pentadecane, and n ‐heptadecane , , .…”

Fatty Acid Deoxygenation in Supercritical Hexane over Catalysts Synthesized Hydrothermally for Biodiesel Production

et al. 2019

Deposition of catalytically active metal‐containing compounds on solid porous supports by using superheated (subcritical) water is a promising way to produce materials with unique physicochemical and catalytic properties. The hydrothermal method has been found to give catalysts with high surface area, fine distribution of the active phase, and high catalytic activity. In the current work, the catalytic activities of 10 % Ni and 10 % Co deposited on hyper‐cross‐linked polystyrene (HPS) by the hydrothermal method in the supercritical deoxygenation of fatty acids were compared. 10 % Ni/HPS was found to be the most active catalyst in the deoxygenation of stearic acid in supercritical n‐hexane.
