Impact of ionomer containing particles on the selective mechanical separation processes for PEM water electrolyzer recycling (Id 402)

Bachelor theses / Master theses

Water electrolyzer is one of the promising technologies to produce green hydrogen as an energy source to reach carbon neutrality. Hitherto three types of water electrolyzer cells have been established, alkaline electrolytic cells, polymer electrolytic cells, and solid oxide electrolytic cells. To improve their performances and energy efficiency, a wide range of catalysts containing critical raw materials are developed. For instance, Ir-based or Pt-based catalysts are considered state-of-the-art materials in polymer electrolyte membrane electrolyzers (PEMELs). As the demand for hydrogen production increases, the consumption of materials used in water electrolysis is also expected to increase. Therefore, an investigation into the recycling of these materials is necessary for a circular economy. However, a very limited number of studies have investigated on recycling processes of water electrolyzers, especially mechanical separation processes for fine particle mixtures after comminution or delamination processes (below 100 µm).
According to previous study results, the representative materials (Carbon black and TiO2) used for the two electrodes of PEMEL showed a clear difference in their hydrophobicity, so the particles can be separated using these characteristics. (Recovery rate: 97% TiO2, 99% carbon black) However, the catalyst ink coated on the cell electrodes is a mixture of particles and ionomers (Nafion) that act as a binder. The presence of the ionomer might affect their hydrophobicity and play an important role in the separation processes. In order to approximate the composition of actual particles, ionomer-containing particles will be prepared as the material for this study. The influence of the ratio of ionomer on the particle wettability has been studied in the previous student thesis. The purpose of this work is to investigate the influence of ionomer on the separation processes by exploiting methods such as particle liquid-liquid extraction and flotation. Furthermore, for effective separation in the binary particle systems, diverse reactants and organic liquids can be considered.

Investigation of the flow following behavior of lagrangian sensor particles in aerated reactors (Id 398)

Master theses / Diploma theses / Compulsory internship

Foto: Sensor particle next to stirrer with bubbles ©Copyright: Lukas BuntkielData acquisition in large industrial vessels such as bio reactor, biogas fermenters or wastewater treatment plants is limited to local measurement points due to the limited access to the vessel and the non-transparent fluid. To optimize these kinds of plants the three-dimensional flow field and the spatial distribution of e.g. temperature and electrical conductivity inside the vessel needs to be known. This can be done by the autonomous flow following lagrangian sensor particles (LSP) developed at the HZDR. Equipped with a pressure sensor, an accelerometer, two gyroscopes and a magnetometer, the sensor particle can track the flow movement inside of the vessels. From this, the flow field can be reconstructed.

To achieve a good flow following behavior, the density of the LSP can be adjusted before they are released into the vessel. While this works well for non-aerated systems, the influence of aeration on the flow following capability is unknown. Another unknown is how the velocities of the rising bubbles and of the continuous phase relates to the velocity measured by the LSP.
Therefore, the aim of this master thesis is to investigate the influence of aeration on the LSPs theoretically and experimentally by tracking the LSP with a camera. This includes the following tasks:

  • Literature research on flow following behavior of large particles in fluids
  • Experiments in a bubble column (330 mm ID) with LSPs and camera
  • Data evaluation to retrieve the fluid velocity, bubble rising velocity and LSP velocity
  • Comparison and conclusions on the flow following capability of LSPs in aerated reactors and comparison to the non-aerated case.

Numerical investigation of particle mixing – internship or final thesis (Id 396)

Student practical training / Bachelor theses / Master theses / Diploma theses / Compulsory internship / Volunteer internship

Foto: Mixing of Fine Particles ©Copyright: Dr. Stephan BodenFine-grained solid particles from various industrial sources, which would otherwise be discarded, should ideally be processed to valuable products or inert residues. Among others, a) shredder fines from electronics and end-of-life vehicles, and b) flue dusts from non-ferrous metallurgical processes are of timely interest. They contain valuable residuals, such as metals, that can be returned to the industrial cycle instead of being landfilled. This is one aim of the Helmholtz project FINEST in which this work is embedded.
The different finest powders need to be mixed and agglomerated for further processing. Our work in the project deals with the granular mixing. One aim is to describe particle flow based on the rheology of the bulk good while describing the mixing process among the particles using a transport equation.
The particle bulk flow in a mixing apparatus can be modelled by CFD, using e.g. FEM. The particle flow field is then coupled with the transport equation to describe the mixing process among the particles.
We are looking for someone with experience in CFD or other modelling to tackle the implementation of this model.

Two phase flow in a mili-/micro-fluidic channel: rare-earth extraction/stripping with/ without magnetic field (student assistant 19 h/week for 3 months + extensions) (Id 395)

Student Assistant

Rare earth elements are group of 17 elements in periodic table. They have unique physicochemical properties which make them essential in many high-tech components, e.g. electric mobility, laser, catalyst etc. The separation of rare earths in industry is mainly done by liquid-liquid extraction, a technique of high environmental footprint. The separation is based on the marginal difference in their affinity against the extractant used. Hence, the separation factor, a parameter quantifying the “separability” of these elements, are small. Normally, hundreds of repeating stages has to take place in plants producing multiple single rare earth products.

We are actively researching a potentially more environmentally friendly alternative approach to improve the separation factor in solvent extraction of rare earths. One approach is to modulate their respective extraction kinetics. Rare-earth ions are affected due to their magnetic susceptibility in a stray field of a magnetic source. The Kelvin force that occurs, can selectively influence the extraction kinetics. Once the goal of establishing a functioning microfluidic flow system has been achieved, a magnetic field can be applied. Various experiments are carried out to separate rare earths in this way. This allows conclusions to be drawn about the reaction kinetics and a deeper understanding of the physical chemical processes can be obtained. For promising candidates there is subsequently the opportunity (Belegarbeit/ Diplomarbeit)) for further employment.

Automatisierte Auswertung von 1D- und 2D-Ramanspektroskopischen Meßreihen (Id 393)

Student practical training / Bachelor theses / Master theses / Diploma theses / Student Assistant / Research Assistant

1D- und 2D-Ramanspektroskopische Meßreihen oder auch Maps liefern detaillierte ortsaufgelöste chemische Informationen über die untersuchten Proben. Damit kann z. B. die Komponentenverteilung in Stoffgemischen quantitativ bestimmt oder die Homogenität einphasiger Proben gezeigt werden. Andererseits lassen sich lokale Strukturveränderungen, Spannungszustände, Stapelfolgenänderungen in 2D-Materialien und Punktdefekte charakterisieren. Voraussetzung dabei ist eine möglichst engmaschige Datenerfassung bis hin zur Auflösungsgrenze der verwendeten Laserstrahlung sowie eine große Anzahl an Messpunkten. Mit modernen Spektrometern sind Messzeiten im Sekundenbereich gut realisierbar. Die Umsetzung der spektroskopischen in eine chemische Information erfordert dann die Extraktion von Parametern wie Schwingungsfrequenz, Intensität und Linienbreite durch Spektrenanpassung. Die Gerätesoftware bietet dafür nur eingeschränkte Möglichkeiten.
Im Rahmen einer Graduierungsarbeit oder Hilfstätigkeit soll in Zusammenarbeit mit dem HZDR-Rechenzentrum ein Auswertealgorithmus für die automatisierte Auswertung von 1D- und 2D-Ramanspektroskopischen Meßreihen entwickelt, an Beispielen getestet und dokumentiert werden.

Experimental investigation of Taylor bubble shape in narrow tubes with constrictions (Id 390)

Bachelor theses / Master theses / Diploma theses / Compulsory internship / Volunteer internship

The presence of geometrical singularities in pipes may significantly affect the behavior of two-phase flow and subsequently the liquid film thickness or bubble shape. Therefore, it is an important subject of investigation in particular when the application concerns industrial safety and design.
In this work, the shape of individual air Taylor bubble in vertical tubes with constrictions subjected to counter-current liquid is experimentally performed and the influence of the obstacle on the bubble shape is analyzed. The restrictions that the constrictions on narrow tubes imposes on the motion of the interface, and its effect on the bubble shape, will be addressed in terms of geometrical and flow parameters.

In this work, the student will experimentally investigate and record high quality images and gain knowledge about experimental work regarding two-phase flow, image acquisition with MATLAB and data organization. The results will lead to the development of a flow regime map in function of diameter and viscosity.

Internship on experimental investigation of aerosol propagation (Id 381)

Student practical training / Compulsory internship / Volunteer internship

Background:

Currently, there is a broad discussion whether ventilation by frequent window opening is sufficient for providing a sufficient amount of fresh air or if technical air purification devices based on e.g. HEPA filters are better solutions for public spaces. Furthermore, there is another discussion ongoing, whether a well-guided laminar flow or a high degree of mixing within a room is more beneficial. The latter, on the one hand distributes the potentially virus-laden aerosols in the whole room, but on the other hand reduces the peak concentrations of these aerosols clouds by magnitudes.

Objectives:

The objective is to perform aerosol propagation experiments and to estimate the potential aerosol inhalation of people in dynamic situations. To achieve this, an aerosol generator will be used in a demonstrator room under different flow conditions. The data from different scenarios will be processed in order to obtain a transference function that can relate the aerosol source with the aerosol receivers.

Tasks:

  • Literature survey
  • Aerosol experiments in different scenarios.
  • Post-processing of the results.

Numerical simulation of particles in rising gas bubbles (Id 356)

Student practical training / Master theses / Student Assistant / Compulsory internship / Volunteer internship

The separation of aerosol particles by a moving gas-liquid fluidic interface is central to a wide variety of industrial and natural applications, among which stand out air purification systems and precipitation scavenging. The particle size significantly affects the separation rate. The diffusion of particles in the nanometer range is largely dominated by molecular diffusion. In this regime, predictive models accurately estimate the separation rates. Model inaccuracy increases, however, significantly when the particle size ranges from 0.1 μm to 2.5 μm. In this impaction-dominated regime, the complex interplay between the flow dynamics on both sides of the fluidic interface and the particle inertia makes it difficult to develop suitable models.
In this work, the student will numerically investigate whether enforcing bubble deformation into a non-spherical shape leads to a higher deposition rate, hereby making the particle separation process more efficient. The results will lead to the development of an improved and reliable separation model accounting for the deformation of the fluidic interface and the associated flow changes.

Self-organized nanopattern formation on crystalline surfaces of III-V semiconductors (Id 341)

Master theses / Diploma theses

Foto: AFM images of ion-induced surface patternings ©Copyright: Dr. Denise ErbVarious metals, semiconductors, and oxides form regular nanoscale surface patterns in a complex process of self-assembly under low energy ion irradiation. Depending on both instrinsic factors of the material and externally controllable irradiation conditions, nanopatterns of very different morphologies will form, making ion-induced pattern formation a highly complex process. We study this process with regards to the material properties of various elemental and compound semiconductors, their crystal structure and surface orientation, the influence of irradiation parameters, and the patterning kinetics. Thereby, we expect to obtain new insights into the complex process of ion-induced nanopattern formation in technologically relevant materials.

We offer several projects, focussing each on a specific semiconductor material and its behavior under ion irradiation. These projects comprise the preparation of nanopatterned surfaces by low energy ion irradiation, imaging these surfaces surfaces by atomic force microscopy and electron microscopy, the quantitative analysis of these data, as well as simulating the patterning process based on continuum equations or kinetic MonteCarlo models.
The experimental work on these projects should result a diploma or M.Sc. thesis in physics, material science, or a related field of study. The provide an introduction to research at a large scale facility (Ion Beam Center IBC) and opportunities for networking with HZDR specialists on nanoscale surface modification and characterization.
