Small amounts of inorganic salts like sodium carbonate and calcium acetate were used as impregnants to pulverized limestone, which was then calcined in a powder-particle fluidized bed (PPFB) in nitrogen atmosphere at ambient pressure. Impregnation of 6-μm limestone with 1 mass% sodium carbonate and 1 mass% calcium acetate lowered the decomposition temperature by 30 K, making a 10% increase of calcination conversion at 1073 K. Additive impregnation involving calcium acetate produced macropores… CONTINUE READING
