Lignin, an abundant renewable biopolymer found in plant cell walls, is enriched phenolic units within its complex molecular structure. Unlocking potential as alternative feedstock (bio)refining has posed a long-standing challenge, even though it holds immense promise for replacing fossil-derived and aromatic compounds. This study focuses on fast pyrolysis effective thermochemical depolymerization method of lignin, coupled with the situ catalytic upgrading aiming to produce valuable bio-oil dealkoxylated (alkyl)phenolic Lignin was isolated via organosolv process from beechwood sawdust (hardwood biomass). Various acidic aluminosilicate catalysts (e.g., zeolites, such ZSM-5, Beta USY, amorphous silica alumina) were applied, having different Si/Al ratio, porous properties. Fast experiments conducted fixed-bed bench-scale reactor at two distinct temperatures (500 600 °C), employing contact times lignin-to-catalyst ratios. Non-catalytic revealed that higher temperature, significantly influences bio-oil's composition yield, resulting conversion initially formed alkoxy-phenols alkyl-phenolic compounds, reaching 47% relative concentration oC, while also yielding high amount up 43 wt.%. Among tested, zeolite ZSM-5 (Si/Al=40) proved be most efficient, shifting chemical profile (mainly BTX) 57%, owing unique microporous structure acidity. Depending catalyst type, balance between BTX monomer aromatics naphthalenes observed. well obtained products (bio-oil, non-condensable gases, char/coke-on-catalyst) thoroughly characterized using various analytical techniques. The results associated physicochemical properties catalysts, providing insights into underlying reaction mechanisms.

Lignin is one of the main structural components lignocellulosic biomass and can be utilized to produce phenolic compounds that converted downstream cycloalkanes aromatics, which are useful as drop-in road or aviation biofuels. Within this study, hydrodeoxygenation model phenolic/aromatic surrogate mixture simulating light fraction lignin fast-pyrolysis bio-oil was performed under mild reaction conditions. Ni/BEA zeolite selected a catalyst investigate conversion product selectivity alkyl phenols (phenol, catechol, cresols), methoxy-phenols (guaiacol, syringol, creosol), aromatics (anisole, 1,2,3-trimethoxybenzene) dimer (2-phenoxy-1-phenyl ethanol) towards (alkyl)cycloalkanes. The eleven aromatic then studied by investigating effect conditions (temperature, time, H2 pressure, concentration, catalyst-to-feed ratio). in range 80–100%, 37–81% (alkyl)cycloalkane yield, being strongly dependent on complexity/side-chain group ring. Regarding mixture, 59–100% achieved, with up 72% yield C6–C9 cycloalkanes. Characterization spent catalysts showed led carbonaceous depositions catalyst, limited lower temperatures longer conditions, while after regeneration, physicochemical properties partially recovered.

For liquid organic hydrogen carrier (LOHC) technology to be competitive with other H 2 ‐storage methods, it is crucial reduce the cost of LOHC materials occupying high proportion embodied energy required for system implementation. Promising approaches are convert crude or waste feedstock into and utilize sources obtained from various routes. Thus, in this review, state‐of‐the‐art advances sustainable LOHC‐based storage using feedstock, associated their conversion materials, coupling obtain high‐purity without separation purification highlighted. Petroleum like light cycle oil pyrolysis fuel used after liquid–liquid extraction, combined distillation/hydroprocessing, one‐pot hydrotreating–hydrocracking. In case converting renewable resources (e.g., biomass plastic waste), depolymerization followed by hydrodeoxygenation an effective approach. To storage, catalysts should designed synthesized toward activating hydrogenation reaction at lower temperatures, along CO resistance. Consequently, context provides guidance development accelerate its commercialization.
