Project Description
Hydrogen is a highly attractive energy carrier, but its practical use is limited by its low volumetric energy density, high explosivity, and problems with material compatibility. One strategy to overcome these challenges is to convert H2 into other molecules such as ammonia or methane. For the storage, transport, and utilization of ammonia, however, efficient purification is required. Gas separation by membranes is one promising approach.
In this project, the modification of polymeric membranes by incorporating different additives is investigated. Gas transport is studied by measuring the sorption capacities of the target gases using a microbalance (MSB) and estimating their diffusion coefficients. Subsequently, single‑gas permeation experiments are carried out using the time‑lag method, allowing the determination of permeability, diffusivity, and solubility.
To obtain more realistic separation data, mixed‑gas permeation experiments are also performed. Gas mixtures with different compositions are prepared, and mixture permeabilities are measured in order to evaluate the real (mixed‑gas) selectivity of the modified membranes.
