• 中文摘要： 本研究以熱重分析方法探討氧化鐵對氧化鎂顆粒吸附二氧化硫的增進效果。我們利用表面積測定儀,測量反應不同階段固體樣品的小孔表面積、小孔體積和小孔分布。有些樣品利用X光繞射儀分析其成分。實驗結果顯示:增加 Fe/ sub 2/O/sub 3/的量,降低Fe/sub 2/O/sub 3/的粉粒大小或提高硫酸化溫度均可提昇增進效果。 Fe/sub 2/O/sub 3/對SO/sub 2/氧化生成SO/sub 3/的觸媒效果可能是氧化鐵增進氧化鎂顆粒吸附二氧化硫的主要原因。
• 英文摘要： The adsorption of SO/sub 2/ by MgO pellet with Fe/sub 2/O/sub 3/ additive was investigated by thermogravimetric method. Surface areas, pore volumes and pore size distributions of pellet at different stages of reaction were determined by a surface area meter. The compositions of some solid samples were analyzed by X-ray diffractometer. Experimental results indicated that the reaction rate could be enhanced by increasing the amount of Fe/sub 2/O/sub 3/, decreasing the grain size of Fe/sub 2/ O/sub 3/ or increasing the sulfation temperature. The enhancement of the adsorption of SO/sub 2/ is probably due to the catalytic effect of Fe/sub 2/O/sub 3/ on the oxidation of SO/sub 2/ to form SO/sub 3/ which is captured by MgO.
