The report presents the results of a study to determine the applicability of metal oxides to the development of new processes for SO2 removal. The oxides of 48 metals were screened according to the thermodynamics of their reaction with sulfur oxides to eliminate from consideration as potential sorbents those oxides that were not capable of reducing the sulfur oxide concentration in exiting flue gas of power plants to 150 ppm. Thermodynamic studies resulted in an extensive compilation of experimentally determined and estimated thermodynamic data. The result of the thermodynamic screening process was reduction of the field of potential sorbents to the oxides of sixteen metals, most of which appear in Groups VI, VII, and VIII of the periodic table. The remaining potential sorbents were prepared in a kinetically active form and the rates of their reaction with SO2 in a simulated flue gas atmosphere were determined using isothermal gravimetric methods. The economic feasibility studies consisted of equipment design and sizing and estimation of the capital investment and gross annual operating cost for a sorber-regenerator system using a fluidized bed model.
