In this work, we investigate the pyrolysis behavior of silicone aerogels through experiments and ReaxFF molecular dynamics (ReaxFF MD) simulations, revealing the impact of silicone side groups on their high-temperature stability. The introduction of methyl, vinyl, and phenyl groups through modifying the crosslinker side chains in aerogels, due to their steric hindrance effects and higher bond energies, inhibits the occurrence of cleavage reactions, thereby improving the thermal stability of the material and providing a basis for material design. We obtained kinetic parameters of the pyrolysis process, including activation energy, pre-exponential factor, and reaction mechanism functions, through thermogravimetric analysis, thereby establishing an accurate and reliable decomposition kinetics model. Fast pyrolysis experiments, alongside ReaxFF MD simulations, systematically elucidated the pathways for forming of gaseous, liquid, and solid products during thermal decomposition. Pyrolysis is primarily triggered by the cleavage of Si-C bonds, leading to the cyclization of the Si-O-Si main chain to form cyclic siloxanes. The cleavage of small molecules undergoes a rearrangement reaction, ultimately resulting in the formation of amorphous silica. This study enhances our understanding of the pyrolysis mechanisms of silicone aerogels and provides theoretical insights for improving their thermal stability.</div></div>","PeriodicalId":345,"journal":{"name":"Journal of Analytical and Applied Pyrolysis","volume":"188 ","pages":"Article 107038"},"PeriodicalIF":5.8,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143454627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pyrolysis of thermally thick biomass particles plays a crucial role across several industrial applications. Despite its significance, the enthalpy changes associated with volatile species release and residual biochar formation during the process are often overlooked. Predictive models for the pyrolysis of large particles and designing a new generation of pyrolyzers are crucial, particularly for industrial-scale applications. Thus, this work introduces a comprehensive one-dimensional (1D) model, BioSMOKE1D, to capture the intricacies of pyrolysis in thick biomass particles and aid in designing optimized pyrolyzers. The model integrates a solid-phase kinetic mechanism, transport limitations, and secondary gas-phase tar-cracking reactions. The BioSMOKE1D has been thoroughly validated and exhibits impressive predictive accuracy by replicating various experiments on large biomass particles. The model successfully reproduces temperature measurements, mass loss profiles, and speciation data at lower temperature measurements. However, incorporating gas-phase mechanisms and secondary tar-cracking reactions has achieved better accuracy at higher temperatures (above 650 °C). Unfortunately, to the authors’ knowledge, no experimental data is available for the pyrolysis of large coffee husk particles. Therefore, several parametric analyses are performed to determine the effect of model parameters on the pyrolysis yields for pelletized coffee husks. The findings indicate that biomass particle size, temperature, and initial moisture content significantly affect conversion time, energy consumption, pyrolysis product yields, and species distributions. Larger biomass particle sizes correspond to slower conversion rates and increased energy consumption. This modeling tool holds promises for optimizing the utilization of coffee husks as a renewable energy source, mitigating agricultural waste, and boosting economic growth. Furthermore, the insights from this study provide valuable inputs for optimizing pyrolysis processes in industrial-scale applications of these resources.</div></div>","PeriodicalId":345,"journal":{"name":"Journal of Analytical and Applied Pyrolysis","volume":"188 ","pages":"Article 107028"},"PeriodicalIF":5.8,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
