Abstract:

The primary objective of the program is the development of reactant particles suitable for application in a high temperature O2-N2 separator device. A series of approaches were followed to manufacture reactant particles with the desired properties. One of the most promising methods consisted of preparing the cobalt oxide raw material by decomposing and calcining cobalt oxalate. By proper control of the oxalate precipitation conditions, it was possible to control the cobalt oxalate crystal size. Upon decomposition, the resulting oxide particle size is related to the particle size of the mother crystals. The testing of the reactant particles obtained up to date has continued on schedule. Five Rotary Disc Separator Tests were performed and are reported. In these tests, the performance of pure CoO, supported CoO, and supported Pd particles were measured. Author
