Role of Spent Shale in Oil Shale Processing and the Management of Environmental Residues. Final Technical Report, January 1979-May 1980

摘要

The adsorption of hydrogen sulfide on retorted oil shale was studied at 10, 25, and 60 exp 0 C using a packed bed method. Equilibrium isotherms were calculated from the adsorption data and were modeled by the Langmuir, Freundlich, and Polanyi equations. The isosteric heat of adsorption was calculated at three adsorbent loadings and was found to increase with increased loading. A calculated heat of adsorption less than the heat of condensation indicated that the adsorption was primarily due to Van der Waals' forces. Adsorption capacities were also found as a function of oil shale retorting temperature with the maximum uptake occurring on shale that was retorted at 750 exp 0 C. (ERA citation 06:010315)
