Shadow imaging of particle dynamics and dissolution rates in aqueous solutions for hydrogen production

This paper presents experimental studies of particle dynamics, dissolution and transport processes for hydrogen production and thermochemical water decomposition. The processes involve multiple steps, some consisting of multiphase reaction systems. It examines the importance of design optimization of gas–solid–liquid phase systems and process integration of a thermochemical copper–chlorine cycle for hydrogen production. The dissolution of copper (I) chloride particle in hydrochloric acid is examined. This dissolution step is investigated in order to provide a predictive modeling method for more complex multiphase reacting systems.
