Summary: In this study, the physico-chemical characterization, pyrolysis kinetics, and thermodynamic analysis of poplar wood, eucalyptus wood, and their binary blend were investigated using TGAthermograms obtained at different heating rates. The kinetic parameters were determined using model-fitting and model-free methods, which resulted in different sets of values. The endothermicity, stability, and energy barrier were found to be different for the different materials. The behavior of the pyrolysis reaction was established using the Criado method.

Summary: Biochar catalyzes polymerization of volatiles in pyrolysis, increasing char formation and decreasing gas formation. The char produced in catalytic pyrolysis is oxygen-rich, aliphatic, with low thermal stability. Biochar catalyst also promotes the formation of larger fused ring structures in phenolics. The interaction between biochar and volatiles removes defective structures in the large aromatic structures of the biochar catalyst.

Summary: The biochemical composition of wood, bark, and leaves affects the characteristics of pyrolysis products. Wood yields the highest amount of bio-oil and the lowest amount of gases, while leaves produce a high yield of gases due to the high content of inorganic species. Leaves and bark produce different types of organic compounds compared to wood, resulting in lower heating value, energy density, thermal stability, and comprehensive combustion index in their biochar. The pyrolysis temperature and feedstock composition also affect the evolution of biochar functionalities.

Summary: The pyrolysis characteristics and kinetics of pine wood with iron-containing petrochemical sludge ash were studied, showing that the presence of PSA promoted the conversion of PW. Thermodynamic analysis revealed a gradual loss of oxygen from Fe2O3 in PSA during co-pyrolysis. Kinetic parameters showed a decrease in activation energy with PSA addition, with the most suitable kinetic models being D-3 and D-4 for PW and its mixtures with PSA, respectively.

Summary: In this study, the fast-growing wood Macaranga gigantea was pyrolyzed and the pyrolysis products were characterized and their formation kinetics were studied. The results showed that increasing the pyrolysis temperature and time increased the yield of liquid and gas products and the concentration of cellulose, hemicellulose, and lignin-derived compounds, but decreased the biochar yield. The pyrolysis products mainly contained phenolic compounds and their derivatives, eugenols, furans, aldehydes, and ketones. The thermal decomposition of M. gigantea required temperatures higher than 300 degrees C to optimize thermal decomposition and carbonization of lignin, cellulose, and hemicellulose. The pyrolysis kinetics of M. gigantea wood occurred through four main stages.

Summary: Densified wood (DW) and lignin modified wood (MW) were investigated for their thermal decomposition and combustion behaviors. MW and DW showed improved thermal stability and increased char yield. A numerical model was used to simulate the pyrolysis behaviors and the results matched well with the experimental data. Cone calorimetry tests revealed that delignification and densification delayed ignition time and DW formed a compact char layer, slowing down the heat release rate.

Summary: Waste particleboards, generated from discarded furniture and building materials, can be efficiently utilized as an energy source through pyrolysis technologies. This study explores the co-pyrolysis treatment of waste particleboards and wood, and finds that blending wood with waste particleboards can improve the pyrolysis reactivity and distribution of pyrolytic compounds. The highest yield of pyrolysis products is achieved when the blending ratio of wood is 50%.

Summary: The devolatilization kinetics of coal, poplar wood, and biomass blends were studied using TGA and FFR. The CPD model failed to accurately simulate the results, while the global model required the use of fitted values of various parameters to obtain agreement between simulated and measured data. It was found that the activation energy for wood was lower than for coal, and blending coal with 20% wood resulted in a decrease in activation energy. Furthermore, the devolatilization times for blended samples were similar to or even lower than that of wood, suggesting the presence of synergies.

Summary: The study found that poplar trees grown in plots with wider spacing have higher gas permeability, and kerosene showed significantly higher permeability compared to water. Thermal modification increases gas permeability and the decrease in wettability caused by thermal modification results in a significant increase in both water and kerosene permeability values.

Summary: In this study, the pyrolysis process of low-ash coal and high-ash coal was investigated, revealing the pyrolysis mechanism of coal, non-isothermal kinetics, and the interaction between minerals and organics. The findings showed that coal pyrolysis occurs in two steps, and high-temperature inner minerals can promote graphitization. After demineralization, the distribution of pyrolysis activation energy becomes more concentrated.

Summary: Efficient electrical energy conversion can be achieved by refining the size of nonprecious metal-based catalysts and confining them in multiheteroatom-doped hierarchical porous carbon. The ultrasmall Mo2C nanocrystals (us-Mo2C) embedded in N and S double-doped hierarchical porous carbon show improved hydrogen production efficiency due to synergistic effects of size-controlled Mo2C, multidoped heteroatoms, and multiscale assembly structures. This study paves the way for constructing ultrafine nanocrystals and high-value conversion of waste biomass.

Summary: Metal-organic frameworks (MOFs) have attracted widespread attention due to their structural diversity and multifunctionality, but their further practical applications are limited by their powdered crystalline state. However, compounding MOFs with self-supporting porous materials with good processibility can effectively stabilize the powdered MOFs. Wood, with its natural multidimensional channel structure and excellent mechanical stability, is highly compatible with MOFs. MOF particles can be uniformly loaded onto the wood channel through physical adsorption, hydrogen bonding, or reaction with hydroxyl and carboxyl groups in the fibers. Ultimately, synthesis of MOF@wood composites with new functions shows great potential in interdisciplinary research.

Summary: Airborne particulate matter pollution, including nanoscale particles, has become a public health threat due to emerging infectious diseases and indoor and vehicular environmental pollution. However, current indoor air filtration units face limitations in terms of cost, energy consumption, and size, result in trade-offs between PM0.3/pathogen interception, PM removal, and air resistance. In this study, a two-dimensional continuous cellulose-sheath/net with a unique dual-network corrugated architecture was designed and synthesized to achieve high-efficiency air filtration and even surpass the performance of N95 particulate face masks.
