Dataset description

Data relating to study exploring the phenomenon of in situ generated gas retention within densely packed cylindrical ion-exchange pellets. Initially, discrete element method (DEM) simulations were used to identify pertinent contact packing parameters, rigorously validated through packing experiments. Calibrated values for dynamic and static friction, and the coefficient of restitution were found in ranges of 0.8–1.0, 0–0.2, and 0–0.2, respectively, with the importance of dynamic friction highlighted. The DEM validation process achieved a packing fraction that exhibited < 4 % deviation from experimental data, with some cylinder alignment observed near the column base. Additionally, laboratory-scale gas generation tests were conducted to replicate the retention of hydrogen within densely packed beds, achieved through the decomposition of hydrogen peroxide. X-ray computed tomography was then used to quantify bubble population size and growth within the beds.
