Production of oxygen-containing fuels via supercritical methanol hydrodeoxygenation of lignin bio-oil over Cu/CuZnAlOx catalyst

Xiangchen Kong et al.

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: Selective transfer hydrogenolysis of lignin-derived aromatic ethers using a non-noble metal-based nanostructured catalyst (NiO(x%)/SnO2) was successfully achieved with high conversion and selectivity. The catalyst exhibited synergistic effects between NiO and SnO2 nanoparticles, leading to efficient hydrogen transfer and interface formation. The study provides a promising strategy for the selective production of aromatic compounds from lignin-derived ethers.

Catalytic depolymerization of lignin via transfer hydrogenation strategy over skeletal CuZnAl catalyst

Yao-Bing Huang et al.

Summary: This study reports the use of non-precious skeletal CuZnAl catalysts for the depolymerization of lignin dimers and real organosolv lignin through catalytic transfer hydrogenation (CTH) method. The results show that under mild reaction conditions, typical lignin dimers and birch organosolv lignin can be effectively converted into aromatics and alcohols. It is found that the water brought by the wet catalyst promotes the cleavage of the C-O bonds. This study provides an economical and environmentally-friendly method for the selective cleavage of lignin into value-added chemicals, and has great potential for industrial applications.

Catalytic hydrogenolysis of lignin in ethanol/isopropanol over an activated carbon supported nickel-copper catalyst

Chongbo Cheng et al.

Summary: In this study, catalytic hydrogenolysis of organosolv poplar lignin was conducted using NiCu/C catalysts in ethanol/isopropanol solvent, achieving high yields of phenolic monomers. The introduction of Cu in catalysts promoted the hydrogen donor process of the solvent and facilitated the cleavage of lignin linkages, resulting in decreased molecular weight of bio-oil. The possible lignin dimer type structures were proposed and identified by MALDI-TOF MS, providing a better understanding of NiCu/C catalyzed lignin depolymerization.

Catalytic ethanolysis of Xilinguole lignite over layered and mesoporous metal oxide composites to platform chemicals

Zhan-Ku Li et al.

Summary: Catalytic ethanolysis of lignites using a series of catalysts showed increased yields of ethanol-soluble portions, especially with CuMgAlOx and ZnMgAlOx catalysts possibly due to the amount of H-2 produced from ethanol. This approach can produce four major platform chemicals, including arenes, phenols, alcohols, and esters, with aromatic rings being reserved and distribution of chemicals tunable by altering catalysts. Proposed pathways for the catalytic ethanolysis were also discussed.
