København og omegn

Membrane reactors based on hydrogen selective membranes can achieve significantly higher power generation efficiencies for water gas shift reaction. Among the available hydrogen selective membranes, palladium metal-based membranes have superior selectivity; however, they are easily prone to poisoning in carbonaceous fuels. Alternatively, ceramic membranes, particularly, silicon carbide (SiC) membranes showed excellent potential due to their high mechanical strength, good thermal and chemical resistance, superior hydrothermal stability and good selectivity for hydrogen with reasonable flux.

In this project, we are aiming to develop multilayer silicon carbide flat architectures with graded porosity. The architecture will consist of macro-porous support layer, on which an intermediate meso-porous layer, and finally the micro-porous layer will be deposited. The support layer will be fabricated using extrusion process using SiC powders and the intermediate layer will be fabricated using dip-coating/sol-gel methods using nano-SiC powders and/or precursors. The final functional layer will be deposited using SiC polymer precursors. The process parameters for multi-step sintering and co-sintering of the fabricated layers will be investigated. Physical and chemical characterization of the individual layers and multilayered structured will be carried out. 

The execution of the project will take place at our state-of-the-art laboratories and the student will acquire the following skills.

-        Particulate ceramic processing

-        Wet-chemistry based ceramic processing

-        High temperature sintering processes

-        Physical characterization – Mercury porosimetry, surface area analysis, particle size analysis

-        Structural characterization - X-ray diffraction analysis, Scanning electron microscopy

-        H2 selectivity and flux measurements.

General understanding of physics, chemistry and materials science is required; lab working experience is preferred but not essential. Ability to follow the instructions along with independent thinking and quick learning skills are a plus.
