AN EUROPIUM-CHLORINE -OXYGEN-HYDROGEN CYCLE FOR THE PRODUCTION OF HYDROGEN AND OXYGEN FROM WATER

摘要

A Eu-Cl-O-H cycle for the thermal decomposition of H20 to H2 and 02 is considered with the five steps.n1. EuCl3(s) - EuCl2(s) + Cla(g)n2. 2EuCl2(s) + 2HCl(g) + 12H20(X) - 2EuCl3-6H20(s) +H3(g)n3. 2Eu.Cl3-6HaO'(s) -2EuCl3(s) + 12H20(g)n4. llHa0(g)-.llH20(£)n5. Cl2(g) + H20(g) - 2HCl(g) + 1/2O2(g) The thermodynamics for the reactions in this cycle are summarized from a literature review. Exploratory laboratory studies of reactions 1 and 3 are described.
