Thermochemische Aufarbeitung von Stahlwerksstäuben und -schlämmen zur Zink- und Eisenrückgewinnung
(2024)
Stahlwerksstäube und -schlämme enthalten in der Regel Schwermetalle wie Zink, Blei und Cadmium, die ein direktes Recycling verhindern und diese Stoffe potenziell umweltgefährdend machen. Um diese Schwermetalle aus den Materialien zu entfernen, werden drei thermochemische Verfahren zur Aufarbeitung von Gichtgasschlamm, Elektroofenstaub und ähnlichen Stahlwerksstäuben vorgestellt. Zum einen kann die Mischung von Elektroofenstaub mit chloridhaltigen Lösungen, wie sie z. B. in der Titandioxidproduktion anfallen, gemischt werden, um bei der thermischen Behandlung Schwermetallchloride zu effektiv verdampfen. Weiterhin kann der im Gichtgasschlamm enthaltene Kohlenstoff genutzt werden, um in Mischungen aus Gichtgasschlamm und Elektroofenstaub bei der thermischen Behandlung als Reduktionsmittel zu wirken. Dieses Verfahren führt zur Rückgewinnung von Zink und metallischem Eisen und wird im Technikums- und Pilotmaßstab erprobt. Abschließend wird die Nutzung von Wasserstoff als Reduktionsmittel für Elektroofenstaub vorgestellt. Hierbei lässt sich der Reststoff potenziell klimaneutral in Eisenschwamm umwandeln, wobei die chemischen Grundlagen anhand von DTA-Experimenten und thermodynamischen Simulationen ergründet werden.
Sunlight is an almost unavoidable environmental cue and plays a fundamental role in the biology of pro- and eukaryotic organisms. To cope with sunlight-associated stresses e.g., high temperatures, UV radiation with associated DNA damage, accumulation of reactive oxygen species (ROS), desiccation and osmotic stresses, it is important for organisms to accurately sense and respond to changes in light. The benefits of light are obvious for green organisms such as cyanobacteria, algae and plants which use light as an energy source (photosynthesis). Less apparent are other light-dependent processes such as light-driven DNA repair by photolyases (photoreactivation) or ion pumping by microbial opsins. Fungi that can share light-flooded habitats with phototrophs may profit from their excess photosynthetic products. Rock-inhabiting Dothideomycetes and Eurotiomycetes including Knufia petricola possess many proteins for absorbing UV/blue, green, red and far-red light, produce the black 1,8 dihydroxynaphthalene (DHN) melanin and orange-red carotenoids, and may live in multispecies biofilms. Here, we are addressing the question to which extent constitutive pigment formation (melanin and carotenoids) and responses mediated by the stress-activated mitogen-activated protein (MAP) kinase contribute to the observed light (UV-B) tolerance of K. petricola.
Rotschlamm fällt in sehr großen Mengen bei der Herstellung von Aluminiumoxid an und wird fast ausschließlich deponiert. Es wird eine neue Technologie vorgestellt bei der das im Rotschlamm enthaltene Eisenoxid mittels Wasserstoffplasma reduziert wird. Es wird ein Reaktionsmechanismus über Titanomagnetit und Hercynit vorgeschlagen.
AbstractRed mud is the waste of bauxite refinement into alumina, the feedstock for aluminium production1. With about 180 million tonnes produced per year1, red mud has amassed to one of the largest environmentally hazardous waste products, with the staggering amount of 4 billion tonnes accumulated on a global scale1. Here we present how this red mud can be turned into valuable and sustainable feedstock for ironmaking using fossil-free hydrogen-plasma-based reduction, thus mitigating a part of the steel-related carbon dioxide emissions by making it available for the production of several hundred million tonnes of green steel. The process proceeds through rapid liquid-state reduction, chemical partitioning, as well as density-driven and viscosity-driven separation between metal and oxides. We show the underlying chemical reactions, pH-neutralization processes and phase transformations during this surprisingly simple and fast reduction method. The approach establishes a sustainable toxic-waste treatment from aluminium production through using red mud as feedstock to mitigate greenhouse gas emissions from steelmaking.
Maintaining and modulating mechanical anisotropy is essential for biological processes. However, how this is achieved at the microscopic scale in living soft matter is not always clear. Although Brillouin light scattering (BLS) spectroscopy can probe the mechanical properties of materials, spatiotemporal mapping of mechanical anisotropies in living matter with BLS microscopy has been complicated by the need for sequential measurements with tilted excitation and detection angles. Here we introduce Brillouin light scattering anisotropy microscopy (BLAM) for mapping high-frequency viscoelastic anisotropy inside living cells. BLAM employs a radial virtually imaged phased array that enables the collection of angle-resolved dispersion in a single shot, thus enabling us to probe phonon modes in living matter along different directions simultaneously. We demonstrate a precision of 10 MHz in the determination of the Brillouin frequency shift, at a spatial resolution of 2 µm. Following proof-of-principle experiments on muscle myofibres, we apply BLAM to the study of two fundamental biological processes. In plant cell walls, we observe a switch from anisotropic to isotropic wall properties that may lead to asymmetric growth. In mammalian cell nuclei, we uncover a spatiotemporally oscillating elastic anisotropy correlated to chromatin condensation. Our results highlight the role that high-frequency mechanics can play in the regulation of diverse fundamental processes in biological systems. We expect BLAM to find diverse applications in biomedical imaging and material characterization.

The benefits of light are obvious for green organisms such as cyanobacteria, algae and plants which use light as an energy source (photosynthesis). Fungi that can share light-flooded habitats with phototrophs may profit from their excess photosynthetic products. Examples are the plant pathogen Botrytis cinerea, the gray mold fungus, and the rock inhabitant Knufia petricola, a microcolonial black fungus which forms multispecies biofilms with bacteria and algae.
Bakterielle Biofilme stellen in medizinischen und industriellen Bereichen ein ernsthaftes Problem dar. Eine der größten gesellschaftlichen Herausforderungen liegt in der zunehmenden Resistenz von Bakterien gegen Biozide, die bei antimikrobiellen Behandlungen eingesetzt werden, z.B. durch übermäßigen Einsatz in Medizin, Industrie und Landwirtschaft oder durch Reinigung und Desinfektion in Privathaushalten. Daher sind neue effiziente bakterienabweisende Strategien, die den Einsatz von Bioziden vermeiden, dringend erforderlich.
Ein vielversprechender Weg zur Erzielung bakterienabweisender Oberflächen liegt in der berührungslosen und aseptischen großflächigen Laserbearbeitung von technischen Oberflächen. Maßgeschneiderte Oberflächentexturen, ermöglicht durch verschiedene Laserbearbeitungsstrategien, die zu topographischen Skalen im Bereich von Nanometern bis Mikrometern führen, können eine Lösung für diese Herausforderung darstellen.
In dem Vortrag wird ein Überblick über den aktuellen Stand der Technik bei der subtraktiven Texturierung von Laseroberflächen zur Kontrolle der Biofilmbildung bei verschiedenen Bakterienstämmen und in unterschiedlichen Umgebungen gegeben. Auf der Grundlage spezifischer Eigenschaften von Bakterien und laserbearbeiteten Oberflächen werden die Herausforderungen antimikrobieller Oberflächendesigns erörtert und zukünftige Richtungen aufgezeigt.
Einstufung von Aschen und Schlacken aus der Abfallverbrennung im Hinblick auf die weitere Verwertung

There are two mirror entries in the European Waste Catalogue for bottom ash and slag from waste incineration: 19 01 11* and 19 01 12. Entry 19 01 11* describes a waste material containing hazardous substances. It was shown that only the hazardous property HP14 (ecotoxic) is of relevance for the classification. If substances with the hazard statement code (HSC) H400, H410, H411, H412 and H413 are present in incineration bottom ash (IBA) above certain level the waste is classified as hazardous, otherwise it is non-hazardous (in this case 19 01 12). It was further shown that only Cu, Zn and Pb compounds have an impact on the classification using a summation rule: 100xΣ c(H410) + 10xΣ c(H411) + Σ c(H412). Limit value is 25 percent. It is obvious that H410 substances have the highest impact. Therefore, the knowledge of the elemental composition of IBA is not sufficient because the content of distinct chemical compounds (with the respective molecular weight) is needed. When the exact speciation is not known a worst-case approach has to be applied. A practical guideline for the estimation of HP14 was developed based on the definition of 4 substance groups: 1. Metals and alloys, 2. Water-soluble substances, 3. Oxides and carbonates and 4. Substances not soluble in weak acids. In substance group 1 only fine Zn powder has the HSC H410. Water-soluble substances are assumed to be H410 substances. Their concentrations are, however, regularly below the cut-off value of 0.1 %. The amount of substance group 3 is estimated by a selective extraction with maleic acid. According to the worst-case approach it is assumed that CuCO3xCu(OH)2 and ZnO represent the respective Cu and Zn species in IBA because these substances have the highest stochiometric factor. Even with this worst-case approach results from operators of IBA treatment plant showed that the limit value of 25 % is not exceeded.
The requirements for utilization of IBA in Germany are defined in the Secondary
Building Materials Decree (Ersatzbaustoffverordnung EBV) which was set into force in August 2023. Leaching methods (batch test or column test) with a liquid-to-solid ratio of 2 l/kg are applied. IBA fulfills the requirements for class HMVA-2. Actually, even a classification of IBA as hazardous (i.e 19 01 11*) would not affect utilization but handling and transport.
Here, we show that calcium sulfate dihydrate (gypsum) can be directly, rapidly and reversibly converted to calcium sulfate hemihydrate (bassanite) in high salinity solutions (brines). The optimum conditions for the efficient production of bassanite in a short time (<5 min) involve the use of brines with c(NaCl) > 4 M and maintaining a temperature, T > 80 °C. When the solution containing bassanite crystals is cooled down to around room temperature, eventually gypsum is formed. When the temperature is raised again to T > 80 °C, bassanite is rapidly re-precipitated. This contrasts with the better-known behaviour of the bassanite phase in low-salt environments. In low-salinity aqueous solutions, bassanite is considered to be metastable with respect to gypsum and anhydrite, and therefore gypsum-to-bassanite conversion does not occur in pure water. Interestingly, the high-salinity transformation of gypsum-to-bassanite has been reported by many authors and used in practice for several decades, although its very occurrence actually contradicts numerical thermodynamic predictions regarding solubility of calcium sulfate phases. By following the evolution of crystalline phases with in situ and time-resolved X-ray diffraction/scattering and Raman spectroscopy, we demonstrated that the phase stability in brines at elevated temperatures was inaccurately represented in the thermodynamic databases. Most notably for c(NaCl) > 4 M, and T > 80 °C gypsum becomes readily more soluble than bassanite, which induces the direct precipitation of the latter from gypsum. The fact that these transformations are controlled by the solution provides extensive opportunities for precise manipulation of crystal formation. Our experiments confirmed that bassanite remained the sole crystalline phase for many hours before reverting into gypsum. This property is extremely advantageous for practical processing and efficient crystal extraction in industrial scenarios.
Reliable measurement of the size of polydisperse, complex-shaped commercial nanopowders is a difficult but necessary task, e.g., for regulatory requirements and toxicity risk assessment. Suitable methods exist for the accurate characterization of the size of non-aggregated, stabilized, spherical and monodisperse nanoparticles. In contrast, industrial nanoscale powders usually require dedicated sample preparation procedures developed for the analysis method of choice. These nano-powders tend to agglomerate and/or aggregate, a behavior which in combination with an innate broad particle size distribution and irregular shape often significantly alters the achievable accuracy of the measured size parameters. The present study systematically tests two commercially available nanoscale powders using different sample preparation methods for correlative analysis by scanning electron microscopy, dynamic light scattering, Brunauer–Emmet–Teller method and differential mobility analysis. One focus was set on the sample preparation by embedding nanoparticles in carbon-based hot-mounting resin. Literature on this topic is scarce and the accuracy of the data extracted from cross sections of these particles is unclearly stated. In this paper systematic simulations on the deviation of the size parameters of well-defined series of nanoparticles with different shapes from the nominal value were carried out and the contributing factors are discussed.
