%X Calcination of oganic calcium was carried out in fixed bed, pore structure of tested sample was analyzed with auto-adsorption analyzer, and desulfurization experiment was studied by intelligent sulfur determination analyzer. Specific surface area of calcium magnesium acetate (CMA) was 46.6 m2/g after calcination at 900 degrees C, almost four times of that of limestone. Specific surface area of calcium acetate (CA) were mainly made up of pore of diameter less than 5 nm, and those of CMA was chiefly contributed by middle pore of diameter about 5 nm. Agglomeration of CA occurred in pore of diameter less than 5 nm, while CMA was sintered in whole range of pore size distribution. Agglomeration of organic calcium were slighter. Desulfurization efficiency of organic calcium ranged from 62.28% to 75.55% at 1000 degrees C as calcium/sulfur ratio being one, which was one time more than that of limestone. Perfect pore structure of organic calcium contributes to higher desulfurization efficiency.
