The economic and environmental threat of climate change due to the anthropogenic rise of the CO2 concentration in the earth’s atmosphere is widely accepted. In addition to the utilization of renewable energy sources, the application of carbon capture and storage processes in energyintense industries seems to be unavoidable. This thesis evaluates the utilization of waste-derived fuels in the calcium looping CO2 capture process. The feasibility of continuous CO2 separation by means of a waste-derived fuel fired calciner was successfully demonstrated by experimental investigations in a 1 MWth pilot plant. In these investigations, the boundary conditions were adapted to an application in Waste-to-Energy plants. Over the course of the test series, it was shown for the first time worldwide, that CO2 capture rates of more than 90 % are feasible, while oxyfiring commercially available solid recovered fuels. Based on the experimental data, a process was validated and subsequently applied for the determination of heat and mass balances for the retrofit of a Waste-to-Energy plant. Die wirtschaftlichen und ökologischen Gefahren des Klimawandels aufgrund des anthropogenen Anstiegs der CO2-Konzentration in der Erdatmosphäre sind weithin anerkannt. Neben der Nutzung erneuerbarer Energiequellen scheint die Anwendung von Verfahren zur Abscheidung und Speicherung von CO2 in energieintensiven Industrien unumgänglich. Diese Dissertation bewertet die Nutzung von Ersatzbrennstoffen im Carbonate-Looping Prozess. Es konnte die CO2-Abscheidung aus einem MVA-ähnlichen Abgas durch einen EBS-gefeuerten Kalzinator anhand von experimentellen Untersuchungen im 1 MWth-Maßstab erfolgreich nachgewiesen werden. Im Rahmen der Versuchsreihen wurde weltweit erstmals gezeigt, dass CO2-Abscheidungsraten von mehr als 90 % realisierbar sind. Basierend auf den experimentellen Daten wurde ein Prozessmodell validiert und anschließend zur Bestimmung von Massen- und Energiebilanzen für die Carbonate-Looping Nachrüstung einer Müllverbrennungsanlage eingesetzt.

To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

Waste Biorefinery: Potential and Perspectives offers data-based information on the most cutting-edge processes for the utilisation of biogenic waste to produce biofuels, energy products, and biochemicals – a critical aspect of biorefinery. The book explores recent developments in biochemical and thermo-chemical methods of conversion and the potential generated by different kinds of biomass in more decentralized biorefineries. Additionally, the book discusses the move from 200 years of raw fossil materials to renewable resources and how this shift is accompanied by fundamental changes in industrial manufacturing technologies (from chemistry to biochemistry) and in logistics and manufacturing concepts (from petrochemical refineries to biorefineries). Waste Biorefinery: Potential and Perspectives designs concepts that enable modern biorefineries to utilize all types of biogenic wastes, and to integrate processes that convert byproduct streams to high-value products, achieving higher cost benefits. This book is an essential resource for researchers and students studying biomass, biorefineries, and biofuels/products/processes, as well as chemists, biochemical/chemical engineers, microbiologists, and biotechnologists working in industries and government agencies. - Details the most advanced and innovative methods for biomass conversion - Covers biochemical and thermo-chemical processes as well as product development - Discusses the integration of technologies to produce bio-fuels, energy products, and biochemicals - Illustrates specific applications in numerous case studies for reference and teaching purposes
