Item type:Publication, Access status: with files , Wertstoffe aus Weizenstroh – Konzeptentwicklung und -bewertung im Bioraffinerie-Kontext(2025); In this study, a process concept for wheat straw is developed that enables an effective valorization from hemicellulose and can potentially be implemented in biorefineries. A techno-economic analysis of existing utilization methods is used to derive feasible alternatives and their requirements. The concept and the experimental investigations are geared towards energy-efficient and resource- efficient feedstock utilization with hydrothermal pretreatment. To evaluate the concepts based on mass and energy balances, the experimental results are transferred to suitable process models and optimization potentials are identified.Publicationtype: Doctoral Thesis90 47 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Pentosane aus Bioethanolschlempe – Untersuchung von Prozessoptionen für DünnschlempeThe increasing demand for dietary fibre in human and animal nutrition requires the use of previously unused resources. Pentosans, a major source of dietary fiber in cereals, are also found in bioethanol stillage, a by-product of bioethanol production. This work investigates options of producing and enriching pentosans from bioethanol stillage. For this purpose, analytical methods for the pentosans are developed and the stillage is comprehensively characterised. The results show that pentosans are particularly enriched in the liquid phase of the thin stillage. The process developed on this basis comprises a solid-liquid separation, a solubilization step and further purification by means of filtration. In this way, a product with a pentosan content of more than 50 %DM can be obtained.Publicationtype: Doctoral Thesis84 40 - Some of the metrics are blocked by yourconsent settings
