Special Issue Information

Dear Colleagues,

In response to the pressing global challenges posed by the rapid depletion of fossil fuels, the escalating demand for alternative energy resources, and the imperative requirement for sustainable processes, there has been a significant focus on biomass conversion to value-added chemicals. This heightened awareness addresses the severe effects of climate change and the energy crisis. Biomass resources, comprising a diverse array of organic materials, are recognized as potentially the largest renewable global energy source. These resources can be categorized based on their original composition, source, and potential conversion technologies. Over the past decade, biomass conversion has been the subject of extensive research, encompassing catalyst innovation, establishment of reaction mechanisms, process optimization, and more.

In recent years, the focus on biomass conversion has been particularly pronounced in Asia, reflecting a growing recognition of its potential as a sustainable energy source. This Special Issue, entitled “State-of-the-Art Catalytic Conversion of Biomass and Their Derivatives in Asia”, will collect and showcase impactful manuscripts that explore the catalytic conversion of biomass and its derivatives into valuable chemicals and biofuels. Contributions from dedicated researchers at the forefront of advancing biomass catalysis are warmly welcomed.

In the present study, cellulose and lignin with different weight ratios were mixed and pyrolyzed to prepare biochars for organic dye pollutant removal in water via Fenton-like catalysis. The results indicated that a higher cellulose content in a biomass precursor could result in a lower biochar yield with a lower carbon content in the biochar. Moreover, with the increase in cellulose content, the resulting biochar had a higher graphitization degree with higher levels of crystallinity, as well as a richer porosity. When using Rhodamine B (RhB) as the dye probe, the biochar derived from a higher cellulose/lignin ratio precursor exhibited better adsorptive performance. It was further found that the biochar could act as a Fenton-like catalyst to activate peroxydisulfate (PDS) and accelerate RhB removal via a degradation route, in which single oxygen (1O2) was identified as the active species. Therefore, the biochar/PDS catalytic system exhibited prominent RhB removal stability in various water matrices with a wide pH application range. This study develops a new approach to prepare biomass-derived biochar with high organic removal capacity via Fenton-like catalysis assisted with adsorption synergy. Full article

Hydrogen production from ethanol steam reforming (ESR) was performed using the synthesized LaNixCu1−xO3−λ perovskite-type catalysts in a continuous two-stage fixed-bed reactor from 450 to 700 °C under atmospheric pressure. The elemental analysis (EA), XRD, SEM, BET, and TGA-DTG technologies were used to characterize the structures and properties of the synthesized catalysts. The thermodynamic equilibrium model, based on the minimization of Gibbs free energy using a non-stoichiometric methodology, was carried out and compared with experimental data. The results demonstrated that the catalytic activity of the perovskite-type catalysts for ESR can be improved after modification with a certain amount of copper (about 0.67 mmol/g) and decreased further with an increase in copper content (about 3.41 mmol/g). The most active catalyst was found to be LaNi0.9Cu0.1O3−λ, with an ethanol conversion value of 96.0% and hydrogen selectivity of 71.3%. The perovskite-type catalysts with an appropriate amount of Cu promoter improved coking resistance and presented excellent stability with no loss of activity over 101 h at 700 °C. Based on the power-law kinetic model with the first reaction order, the activation energy and the frequency factor for ethanol steam reforming by perovskite-type catalysts were calculated. Our studies indicated the enhanced effects of Ni and Cu on the small Ni-Cu bimetallic particles in the water gas shift (WGS) reaction, which could also contribute to the activity and stability of the LaNixCu1−xO3−λ perovskite-type catalysts in hydrogen production.

To address global climate change and the energy crisis, there is an urgent need to meet human demands through utilizing renewable energy sources. The deoxygenation of lipids to produce liquid biofuels has emerged as a promising alternative, particularly for carbon emission reduction in the aviation industry. This review critically examines recent progress in catalyst development and reaction control strategies for lipid deoxygenation. Emphasis is focused on the design of different kinds of catalysts to meet the requirements, including noble metal catalysts, non-noble metal catalysts, and non-noble metal compound catalysts, with strategies such as morphology control, utilization of metal support interactions, and constructing synergistic effects between metal acid centers and metal oxygen vacancies. The reaction networks, mechanisms, and selectivity control strategies for lipid deoxygenation, cracking, isomerization, and aromatization are comprehensively discussed. Finally, we propose that it requires focusing on the precise regulation of multiple active sites to optimizing deoxygenation performance and reusability. It is essential to integrate in situ characterization to deepen the study of structure–active relationships and explore the reaction mechanisms within complex reaction systems. Full article
