Optimization of biogas production from Phragmites australis using first-order kinetic models
DOI: https://doi.org/10.3846/mla.2025.23954Abstract
This study investigates the viability of Phragmites australis, commonly known as the common reed, as a sustainable feedstock for biogas production, emphasizing the effectiveness of pretreatment techniques to enhance biogas production. Given the invasive nature of Phragmites australis, the utilization of its biomass not only addresses environmental management challenges but also contributes to renewable energy solutions. The key objective is to evaluate mechanical and thermal pretreatment techniques on the anaerobic digestion performance of Phragmites australis using the first-order kinetic model biogas’ cumulative production and volatile solids (VS) degradation were estimated. Sensitivity analysis was used to assess how different degradation rate constants and final biogas yield affected the efficiency of biogas generation. The degradation of VS was significantly accelerated by higher temperatures and finer particle sizes. Results indicate that both mechanical and thermal pretreatment significantly enhance biogas yield and degradation rates, milling (<1 cm) and moderate thermal treatment (100 °C, 2 h) providing optimal results. These studies highlight that the selection of appropriate pretreatment methods should be based on their sustainability and effectiveness in terms of reducing energy consumption and environmental impact.

Biodujų gamybos iš phragmites australis optimizavimas, taikant pirmojo laipsnio kinetinius modelius
Santrauka
Šiame darbe tiriamas paprastosios nendrės Phragmites australis panaudojimas biodujų gamybai. Darbe vertinami optimalūs derliaus nuėmimo laikotarpiai bei veiksmingi pirminio apdorojimo metodai, siekiant maksimaliai padidinti metano išeigą. Atsižvelgiant į invazinį Phragmites australis pobūdį, jos biomasės naudojimas ne tik sprendžia su aplinkos taršos mažinimu susijusius iššūkius, bet ir prisideda prie atsinaujinančios energijos gamybos. Šiame tyrime taikomas pirmo laipsnio kinetinis metodas, siekiant ištirti mechaninio ir terminio apdorojimo poveikį Phragmites australis anaerobiniam apdorojimui. Taikant pirmo laipsnio kinetinį modelį buvo įvertinta kumuliatyvinė biodujų išeiga ir lakiųjų kietųjų dalelių (VS) skaidymas. Jautrumo analize buvo įvertinta, kaip skirtingos skilimo greičio konstantos ir galutinis biodujų kiekis paveikė biodujų gamybos efektyvumą. Rezultatai rodo, kad tiek mechaninis, tiek terminis pirminis apdorojimas žymiai padidina biodujų išeigą ir VS skilimo greitį, o malimas ir vidutinis terminis apdorojimas (100 °C, 2 val.) užtikrina optimalius biodujų išeigos rezultatus.
Reikšminiai žodžiai: anaerobinis skaidymas, biodujos, pirminis apdorojimas, Phragmites australis, kinetika.
