Summary: This study demonstrates an effective conversion of xylose into furfural with a selectivity of over 90% using a three-solvent system. The use of an apolar aromatic solvent, a polar organic solvent, and acidic water catalyzes the formation of furfural. The transition of the three-solvent system from biphasic to monophasic conditions under reaction conditions is crucial for achieving high selectivity.

Summary: Furfural production from xylose using p-toluenesulfonic acid as a catalyst in DMSO medium was studied. The optimal catalyst was found to be pTSA-CrCl3 • 6H2O, which achieved a high furfural yield of 53.10% at 120 degrees C. Kinetic modeling showed that the condensation of furfural in the solvent medium could be neglected.

Summary: By investigating the reaction process of glucose in methanol, it has been found that aluminum phosphotungstate and phosphotungstic acid, as representative bifunctional catalysts, have different promotion effects on the reaction. It has been revealed that aluminum ions can accelerate the rate-limiting step by inducing ring opening of the key intermediate, rather than facilitating the isomerization as previously speculated. These findings have significant implications for the rational design of superior catalysts for biomass valorization.

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.

Polyethylene terephthalate (PET) waste, as the most common polyester plastic, can be effectively converted into H2 fuel and terephthalic acid through a novel and simple one-pot strategy. A high H2 yield and carbon conversion efficiency were achieved using a Ru-5ZnO/ mesoporous carbon (MEC) catalyst at a low temperature of 250 degrees C. This sustainable solution has been successfully applied to different types of PET waste and shows great potential for practical applications.

Summary: This study prepared catalysts using Nb2O5 supports with three different crystal structures (pseudohexagonal-TT, orthorhombic-T, and monoclinic-H) and loaded bimetal Ni and Co for the hydrodeoxygenation (HDO) of lignin-derived phenolics. The research found that the structural properties and acidity of the supports and catalysts deteriorated with increasing calcination temperatures. Additionally, the interaction strength between the supports and active metals and the catalyst reduction times were related to the oxygen vacancy content. The best catalyst exhibited complete conversion of reactant and high cycloalkane selectivity.

Summary: This study investigated the co-pyrolysis characteristics, kinetics, gas and liquid products of cellulose and PET mixtures using a two-stage reactor and deep learning approach. The results accurately predicted the thermal decomposition process and synergistic effects using temperature, catalyst, mixing ratio, and heating rate variables. The co-pyrolysis of cellulose and PET led to a reduction in carbohydrates, furans, alcohols, ketones, and phenols, while increasing the content of acids. The introduction of ZSM-11 resulted in an increase in aromatics and a decrease in acids content. This work provides valuable guidance for effective disposal of municipal solid waste and the application of deep learning methods.
