| Solar Production of Hydrogen Using a Cadmium Based Thermochemical Cycle | ||
| Lloyd C. Brown and Bunsen Y. Wong, General Atomics, 3550 General Atomics Ct., San Diego, CA 92121 The Molten Cadmium thermochemical cycle consists of two chemical reactions: Cd(l) + H2O(g) => CdO(s) + H2(g) [350oC] CdO(s) => Cd(g) + ½O2(g) [1450oC] The first experimental hurddle has been overcome. Hydrogen has been produced at reasonable rates in a steam-hydrogen mixture at close to the thermodynamically predicted stoichiometry. The products of the high temperature reaction must be quenched to prevent back reaction. Work has begun on determining the required quench rate. Flowsheets have been developed, based on alternative quench strategies, to aid further process development. Extended Abstract Status: Not Uploaded | ||
