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 pi...
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.
