N2 - The sulfur family of thermochemical processes are the leading candidates worldwide for production of hydrogen (H 2) using nuclear energy. These processes thermocatalytically crack water yielding hydrogen and oxygen. The processes consist of a series of chemical reactions where all the chemicals are recycled in the process except for water. The processes are potentially efficient, scalable to large sizes, and use no expensive chemical reagents; however, these processes have one major disadvantage: high operating temperatures (800 to 900°C). The high-temperature chemical reaction common to all of these cycles is the equilibrium thermal decomposition of sulfuric acid. There is a potential to lower the peak temperature by 200+ °C if the high-temperature decomposition products of sulfuric acid, O 2, H 2O, and SO 2, can be separated from SO 3 using an inorganic membrane. The goal of this project is to conduct proof-of-principle experiments and associated analysis to demonstrate the potential for inorganic membranes to dramatically improve the sulfur family of thermochemical processes. We will present preliminary data of the separation efficiency of the product gases from SO 3.
