Rund ein Drittel (2.529 PJ) der in Deutschland verwendeten Endenergie wird von der Industrie genutzt. Es gibt viele Industriebereiche in denen die Prozessluftaufbereitung eine wichtige Rolle spielt. Beispielhaft ist die Lebensmittel-, die Pharma- und die Halbleiterindustrie zu nennen. In all diesen Bereichen wird Luft mit bestimmten Konditionen benötigt, um Produkte präzise und unter Einhaltung aller Auflagen herstellen zu können. Die Luftaufbereitung ist meist mit einem großen Energieaufwand verbunden. Hierzu ist es erforderlich, Prozesswärme und/oder Prozesskälte zur Verfügung zu haben.
The CO2 uptake on nanoscale AlO(OH) hollow spheres (260 mg g−1) as a new material is comparable to that on many metal–organic frameworks although their specific surface area is much lower (530 m2 g¬1versus 1500–6000 m2g¬1). Suited temperature–pressure cycles allow for reversible storage and separation of CO2 while the CO2 uptake is 4.3-times higher as compared to N2.
The formation and analysis of ten microporous triazolyl isophthalate based MOFs, including nine isomorphous and one isostructural compound is presented. The compounds 1 M – 3 M with the general formula [ M ( R 1 - R 2 - trz - ia ) ] ∞ 3 ·x H 2 O (M 2+ = Co 2+ , Cu 2+ , Zn 2+ , Cd 2+ ; R 1 = H, Me; R 2 = 2py, 2pym, prz (2py = 2-pyridinyle; 2pym = 2-pyrimidinyle; prz = pyrazinyle)) crystallize with rtl topology. They are available as single crystals and also easily accessible in a multi-gram scale via refluxing the metal salts and the protonated ligands in a solvent. Their isomorphous structures facilitate the synthesis of heteronuclear MOFs; in case of 2 M , Co 2+ ions could be gradually substituted by Cu 2+ ions. The Co 2+ :Cu 2+ ratios were determined by ICP-OES spectroscopy, the distribution of Co 2+ and Cu 2+ in the crystalline samples are investigated by SEM-EDX analysis leading to the conclusions that Cu 2+ is more favorably incorporated into the framework compared to Co 2+ and, moreover, that the distribution of the two metal ions between the crystals and within the crystals is inhomogeneous if the crystals were grown slowly. The various compositions of the heteronuclear materials lead to different colors and the sorption properties for CO 2 and N 2 are dependent on the integrated metal ions.
This thesis explores the feasibility and optimization of a solar-thermal sorption system mainly designed to provide cooling but also capable of heating functionalities. Through the development of a black-box model using Python programming, the study delves into the system's performance under various operation modes. Simulation results reveal the effectiveness of adaptive control strategies and pre-heating stages in optimizing efficiency, particularly in cooling modes. In heating assessments, superior performance is observed when utilizing the outdoor coil as the heat source for the heat pump. Challenges related to operational temperature bands are addressed, proposing parallel connections of the heat pump and outdoor coil to enhance performance. Future research directions include refining regression models and incorporating real-time measurement data for improved accuracy, as well as extending simulation duration for comprehensive evaluations. This study contributes valuable insights into the system’s capabilities and applications, laying the groundwork for advancements in heat-driven integrated sustainable energy systems.
