The principal objectives of the proposed research are two-fold: (A) To understand the mechanism and assess the effectiveness of sulfur capture by the chemical calcium magnesium acetate (CMA). And (B) To evaluate the NO{sub x} reduction capabilities of CMA by burning the organic constituents of the chemical (the acetate) and reducing NO to stable N{sub 2} The optimum conditions and the location of CMA introduction in the furnace will be identified. To achieve these goals water solutions of CMA or dry powders of CMA will be injected into hot air or gases simulating the furnace exhaust (containing CO{sub 2}, SO{sub x} NO{sub x}, H{sub 2}O, O{sub 2} etc.) and the composition of gaseous and solid products of the reaction will be monitored. The processes of burning the organic acetate as well as the calcination, sintering and sulfation of the remaining solid will be studied in detail.
