2、效果的影響。在優(yōu)化的實驗條件下，進一步探究低溫等離子改性對復(fù)合鈣基吸附劑脫硫的影響。結(jié)果表明，在最佳實驗條件下，復(fù)合鈣基吸附劑對SO2的單位質(zhì)量吸附量達到24.89mg/g，大于純CaO的脫硫效果；通過低溫等離子處理后的復(fù)合鈣基吸附劑擁有更高的SO2脫除效率，與未改性復(fù)合鈣基吸附劑相比，單位質(zhì)量吸附量提高了61.7%；在SO2和NO的競爭脫除反應(yīng)中，經(jīng)過低溫等離子改性后，復(fù)合鈣基吸附劑脫除污染物向著有利于脫除SO2的方向發(fā)展。關(guān)鍵詞：低溫等離子；復(fù)合鈣基吸附劑；脫硫中圖分類號：X511文獻標(biāo)志碼：A文章編號：1000–6613（201
