Summary: A novel strategy was proposed to produce diesel-like liquid fuel from lignin-derived bio-oil and plant/animal oil through hydrodeoxygenation-in situ esterification. The utilization of both aromatic units and -OCH3 groups of lignin was achieved. Model compounds, guaiacol and lauric acid, successfully produced cyclohexyl laurate and methyl laurate, satisfying the biodiesel standard. The yield of esters reached 112.5 mol % with nearly complete conversion of guaiacol. The presence of an additional -OCH3 group hindered the formation of cyclohexanol while increasing the yield of methanol. Lignin-derived dimers were also efficiently converted into diesel-like liquid fuel rich in esters and cycloalkanes.

Summary: Efficient conversion of lignin-derived bio-oils to cycloalkanes was achieved using bifunctional RuCoWx/NC catalyst prepared by in situ pyrolysis method. The catalyst exhibited excellent hydrodeoxygenation (HDO) activity towards 4-propylguaiacol and rice husk bio-oil, leading to high yields of propylcyclohexane and hydrocarbons, respectively. The stability of RuCoW0.03/NC catalyst was also confirmed after four cycles.

Summary: A copper catalyst modified with propanoic acid was developed for the hydrodeoxygenation (HDO) of crude lignin bio-oil to jet fuel precursors. The modified catalyst exhibited exceptional catalytic performance, improving the yield of jet fuel precursors and reducing the double bond equivalence and aromaticity index of the products. These findings suggest promising avenues for increasing the efficiency of heterogeneous catalysts in the conversion of lignin-based bio-oil to alternative fuels.

Summary: An efficient approach for producing high-quality oxygen-containing fuel from renewable lignin bio-oil has been proposed in this study. The optimized Cu6Ni20/MgO catalyst showed good performance in yielding ethylbenzene and cyclohexanol.

Summary: This study evaluated Al-MCM-41 supported Pd, Co, and Fe catalysts for the fast pyrolysis of lignocellulosic biomass and the upgrading of bio-oil. The results showed that bimetallic Pd-Co and Pd-Fe catalysts exhibited higher yield and stability in the hydrodeoxygenation process. The addition of Pd improved the stability of Co and Fe catalysts and reduced coke formation. The lignin-derived bio-oil mainly contained phenolic compounds, and catalytic upgrading successfully removed oxygen and reduced the amount of tar and heavy components. The Pd-Fe catalyst was identified as a suitable catalyst for upgrading of lignin-derived bio-oil.

Summary: The N-doped bimetallic RuCoNx/NC catalyst prepared by direct pyrolysis of chitin shows excellent hydrodeoxygenation performance due to the continuous spillover of H from Ru to Co and abundant accessible active sites. It can convert 4-propylguaiacol into 92% 4-propylcyclohexanol at 210 degrees C, with 95% selectivity towards propylcyclohexane at 280 degrees C after 6 hours. Reusability tests demonstrate that RuCoNx/NC can be recycled four times without loss of conversion and initial selectivity, indicating its general applicability for HDO of various phenolic compounds.

Summary: This study presents a practical and economical method for upgrading lignin bio-oil by supercritical methanol hydrodeoxygenation (SCM-HDO) using a Cu/CuZnAlO(x) catalyst. The selective production of oxygen-containing fuel was achieved through the hydrogenation of aromatic rings and inhibition of over-deoxygenation reactions. The catalyst activity could be easily recovered through a calcination-reduction process, offering potential opportunities for the production of alternative biofuels from lignin bio-oil.

Summary: Three complementary Kraft lignins and a Soda lignin were characterized by NMR and GPC, with their theoretical yield in monomers calculated based on the analyses. The most recalcitrant Kraft lignin was depolymerized in supercritical ethanol with Pt/C, Ni/C, and Ru/C catalysts, demonstrating the important effect of catalysts on monomers, oligomers, and char yields. The study also showed that lignin structure plays a role in the depolymerization mechanism.

Summary: In this study, various heterogeneous micro- and mesoporous, acidic catalysts were examined for the selective synthesis of Florol (R). The results showed that a mildly acidic, microporous H-Beta-300 catalyst with a SiO2/Al2O3 ratio of 300 performed the best, achieving 72% selectivity and 99% conversion at 40 degrees C with a molar ratio of isoprenol to isovaleraldehyde of 1:5. More acidic zeolite catalysts exhibited slightly lower selectivity, while mesoporous catalysts with mild acidity and no strong Bronsted acid sites had the lowest selectivity.

Summary: A one-pot continuous synthesis of menthols from citral was achieved with high selectivity under specific conditions. Catalyst deactivation over time resulted in a decrease in the selectivity to menthols and an increase in the selectivity to isopulegols. A kinetic model was developed to describe the reaction, taking into account both metal and acid site deactivation, and showed good agreement with the experimental data.

Summary: Bio-oil, derived from renewable sources, is a promising candidate to replace oil-derived products. This study investigates the extraction of guaiacol, an important lignin derivative, from alkanes using glycols and their eutectic mixtures. The results show that the eutectic mixtures have higher selectivity and larger miscibility gaps with the n-hexane phase than the studied glycols, making them more effective in extracting guaiacol.

Summary: This study summarized the one-pot synthesis of menthol from citronellal or citral, which can be conducted in both batch and continuous reactors. The reaction requires a bifunctional catalyst with Lewis acid sites for cyclisation of citronellal and metal particles for its hydrogenation. Different catalyst properties and reaction conditions can affect the yield and selectivity of the desired L-menthol. The study also investigated the performance of the catalyst in a trickle bed reactor and discussed the effect of metal location and synthesis method on catalyst performance.

Summary: In this study, co-processing of n-hexadecane with lignin derived isoeugenol was investigated using low-cost mono- and bimetallic iron and nickel supported on H-Y-5.1 zeolite. Different Fe-Ni metal ratios in the catalyst led to different reaction rates and product distribution. Catalysts with smaller metal particle sizes were more efficient, and 2 wt% Fe - 8 wt% Ni/H-Y-5.1 catalysts exhibited extremely high activity in co-processing.

Summary: A set of low-cost monometallic Fe, Ni, and bimetallicFe-Ni bifunctional H-Y-5.1 catalysts with different metal ratios were synthesized and characterized. The introduction of Fe led to a decrease in strong acid sites and an increase in medium Bronsted acid sites, while the introduction of Ni increased the number of Lewis acid sites. The particle size of iron was approximately 5 nm, while it was about fourfold higher for nickel. XPS demonstrated higher iron content on the catalyst surface compared to nickel. The results also showed strong Fe-Ni nanoparticle interactions, which affected the catalytic performance.
