“…Similar modeling was conducted for a free-falling reactor. Where an average particle size of 200 µm falls freely from the reactor top to interact with the reflux steam, natural convection draws steam from the cold side of the reactor, allowing sufficient residence time for the reactant [9]. In another study, a model was developed to predict the hydrodynamic behavior and conversion of CuCl2 particles and steam using the VM and SCM [10].…”

Hydrogen generation from the thermochemical copper-chloride (Cu-Cl) cycle is a promising clean energy process due to lower operating temperature relative to comparable cycles and can be integrated with solar and nuclear systems. This study focuses on the impact of CuCl2 particle size and morphology in the hydrolysis reaction step. The particle size was studied using crushing and crystallization, and the morphology was analyzed using a scanning electron microscope (SEM). This data was used as input into the shrinking core model (SCM) and compared with previous experimental data. Prior to crushing and crystallization, the material had a monodisperse size distribution with a diameter between 70 -200 µm and a length of 200 -650 µm. After crushing, the material was non-uniform in shape and sizes with a cylindrical or cuboid shape with a diameter of 20 -70 µm and length range of 30 -150 µm. Particles less than 10 µm were spherical in shape. Agglomerated particles forming irregular flakes were observed after crystallization. Furthermore, the SCM indicated that the reaction control step with spherical particle assumption is the most accurate model.
