| Abstract: | The LASL Bismuth Sulfate Cycle includes a solid-decomposition step as an alternative to the high-temperature evaporation and decomposition of concentrated sulfuric acid, with its attendant drying and materials problems. A solids decomposition facility was constructed and used to study the handling of solid sulfates and the kinetics of their decomposition. The decomposition of Bi/sub 2/O(SO/sub 4/)/sub 2/ has been measured as a function of temperature and transit time through a laboratory-scale rotary kiln, constructed from quartz. Temperatures from 973 to 1143/sup 0/K were investigated. The transit time was controlled by varying the slope of the kiln, its rotational speed, and the rate of feed of a bismuth oxysulfate prepared in the prescribed manner. The preparation and characterization of this solid, which has reasonable feeding properties and minimal solution retention, are described. Significant amounts of decomposition were measured in short reaction times at the temperatures investigated. |
