In the present study, combustion mechanisms, thermal kinetics, and phases of combustion were investigated for waste wood samples (untreated pine and treated MDF, plywood and particleboard). Waste wood samples were combusted in air at 10, 20 and 30 degrees C/min heating rates in TGA. The results of TG analysis have shown that thermal decomposition of treated samples takes place at lower temperatures as compared to the untreated pine sample because of the catalyzing effects of the chemicals in the samples. Therefore, there were less flammable products, lower weight losses in the main oxidation region, and decrease in the maximum weight loss temperatures and formation of more char for treated samples as compared to untreated pine sample. Thermal kinetic constants for the samples were calculated by using Coats Redfern Method. In order to find out the mechanisms responsible for the oxidation of the waste wood samples, six solid-state mechanisms of Coats Redfern Method were tested. The results of the Coats Redfern Method have shown that diffusion mechanism is the effective mechanism for all regions of the pine samples. For the main oxidation region, D4 mechanism (Ginstling-Brounshtein equation) was found to be the main diffusion mechanism for pine samples. For the treated samples such as MDF, plywood and particleboard, first-order reaction (F1) was found as an effective mechanism. Treatment of wood with different additives and glues seemed to alter the thermal oxidation process and change the effective oxidation mechanisms. (C) 2009 Elsevier B.V. All rights reserved.

Understanding the role of Ni-based single-atom alloys on the selective hydrodeoxygenation of bio-oils

Seba Alareeqi, Daniel Bahamon, Kyriaki Polychronopoulou, Lourdes F. Vega

Summary: This study explores the potential application of single-atom-alloy (SAA) catalysts in bio-oils hydrodeoxygenation refining using density functional theory (DFT) and microkinetic modeling. It establishes the relationships between stability, adsorptive properties, and activity structures for bio-oil derivatives, providing guidance for the synthesis of cost-effective SAA combinations.

Experimental and computational study on xylan pyrolysis: The pyrolysis mechanism of main branched monosaccharides

Bin Hu, Wen -Ming Zhang, Xue-Wen Guo, Ji Liu, Xiao Yang, Qiang Lu

Summary: This study explored the pyrolysis behaviors and mechanisms of different monosaccharides, including arabinose, galactose, galacturonic acid, and glucuronic acid. The roles of structural differences in these monosaccharides were analyzed, and it was found that glucuronic acid undergoes a special C-C bond breaking reaction during pyrolysis. The findings provide a deep understanding of the pyrolysis chemistry of hemicellulose and the role of different branches.

Summary: Hydrothermal carbonization (HTC) is an effective method for the harmless disposal of municipal sludge (MS) and offers potential applications for the obtained products. Optimizing reaction conditions, coupling with other waste materials, and combining different processes can improve the performance of HTC. Furthermore, HTC contributes to energy recovery and enhances the quality of life cycle assessment.

A 3D computational study of the formation, growth and oxidation of soot particles in an optically accessible direct-injection spark-ignition engine using quadrature-based methods of moments

Florian Held, Jannis Reusch, Steffen Salenbauch, Christian Hasse

Summary: The accurate prediction and assessment of soot emissions in internal combustion engines are crucial for the development of sustainable powertrains. This study presents a detailed quadrature-based method of moments (QMOM) soot model coupled with a state-of-the-art flow solver for the simulation of gasoline engines. The model accurately describes the entire cause-and-effect chain of soot formation, growth and oxidation. Experimental validation and engine cycle simulations are used to identify the root cause of observed soot formation hotspots.
