“…Reported literature on the hydrolysis reaction include experimental studies on three different types of reactors, viz., packed bed, − fluidized bed, and spray reactor. , The laboratory-scale experiments carried out in packed-bed reactors were focused on reaction feasibility, characterization, and kinetics determination. The presence of CuCl as a minor side product was reported by Lewis and Ferrandon from thermal decomposition of CuCl 2 .…”

Hydrolysis of CuCl 2 is the water splitting step of the Cu−Cl thermochemical cycle, where CuCl 2 reacts with steam to produce Cu 2 OCl 2 and HCl. In the present work, this gas−solid reaction was investigated to understand the mechanism and kinetics. Experiments were conducted in a semibatch fluidized bed reactor to study the effect of temperature (275−375 °C), steam mole fraction (0.4−0.9), and reaction time (0−3 h). The challenges due to the hygroscopic nature of the reactant, product agglomeration, and multiple side reactions to achieve smooth and consistent reactor performance were overcome by the addition of inert additives during fluidization. The analysis of the mechanism showed that the desired product Cu 2 OCl 2 is formed initially and further undergoes decomposition to CuO and CuCl 2 . Also, with increasing temperatures, the yield of Cu 2 OCl 2 decreases because of the formation of CuCl from reactant decomposition. The results indicate that a minimum steam mole fraction of 0.5 is required to prevent the formation of side product CuCl in the temperature range of 300−325 °C. The minimum steam requirement for maximum yield to Cu 2 OCl 2 was found to increase with increase in temperature.
