The fundamental understanding of the catalytic performance copper-based catalysts for lignin hydroconversion is delayed compared with empirical optimization catalyst preparation. Herein, we investigate interplay between lignin-abundant oxygen-containing functional groups and Cu active species via β-O-4 linkage hydrogenolysis. Catalyst data elemental spectra characterizing demonstrate dominance Cu0 in catalysis. Remarkably, Cα–OH Cα═O aliphatic chain play critical roles this process, without...
The conversion of crude lignin bio-oil to jet fuels is a highly desirable target for biorefineries, especially in light the global energy crisis. key achieving this goal realistic tuning catalyst efficiency and selectivity expected products. Herein, copper with enhanced activity hydrodeoxygenation (HDO) fuel precursors was developed work. catalyst, copper-doped porous metal oxide, modified series moderate organic acids graft acidic O-groups as potential Brønsted acid sites HDO reactions....
The development of an economic and sustainable catalytic system was crucial for lignin-based biorefinery. Herein, we reported a low-cost Cu/CuMgAlOx catalyst with promising activity toward lignin hydrodeoxygenation (HDO) through H2-free method. Supercritical methanol used as the hydrogen donor, solvent, reactant simultaneously. Guaiacol employed representative model compound to reveal HDO mechanism derivatives. HDOs guaiacol performed at 250, 275, 300, 350 °C durations ranging from 15 120...
Production of jet fuel precursors from waste kraft lignin through a depolymerization and hydrodeoxygenation (DHDO) method with complex copper acid catalyst is reported. The undergoes high degree depolymerization, deoxygenation, hydrogenation, C–C coupling. Monomers dimers molecular weights in the ranges <200 Da 354–452 are obtained optimized yields reaching 93.29 39.30 C% at 360 °C for 8 h, while trimers oligomers higher also generated lower contents. carbon monomers given by incorporation...
Lignin, an aromatic polymer, is a crucial component of lignocellulosic biomass and significant source renewable aromatics found in nature. Lignin constitutes up to 30 wt % generated excess 100 million tons per year from global paper bio-ethanol industries. Unfortunately, most technical lignin produced this manner burned as heat source, without any value-added valorization. The conversion into valuable compounds can significantly increase the profitability biorefineries. However, productivity...
In the field of photocatalysis, crystal phase engineering titanium dioxide is a research hotspot. Titanium heterojunctions often exhibit better photocatalytic performance than single-phase TiO2. Here, two-step hydrothermal and calcination method used to build interface between TiO2 (B) rutile for first time, narrow band gap heterojunction material synthesized. The characterized by transmission electron microscopy (TEM), ultraviolet (UV), X-ray photoelectron spectroscopy (XPS), paramagnetic...
A complex copper acid catalyst (SA-Cu/CuMgAlOx) was developed with boosted catalytic activity for the hydrodeoxygenation (HDO) of lignin-derived phenolics. Remarkably, yields total monomers and cyclohexanes from HDO lignin pyrolysis bio-oil were significantly improved after modification salicylic acid, which increased by 17 40%, respectively, at 300 °C 8 h. The characterizations revealed that acidic oxygen-containing functional groups (−OH −COOH) introduced onto surface without corrosion to...
