固體吸收劑脫除高溫?zé)煔庵袎A金屬研究
摘要: 活性礬土、二氧化硅、硅藻土及煤灰對(duì)高溫?zé)煔庵袎A金屬的脫除都有一定 的效果。通過(guò)模擬高溫?zé)煔庀碌臒嶂貙?shí)驗(yàn),研究了溫度對(duì)這些吸收劑脫除堿金屬的影響 ,并從化學(xué)熱力學(xué)的角度對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行了分析。結(jié)論為4種吸收劑對(duì)堿金屬的脫除都有一 定的效果,但活性礬土和二氧化硅在實(shí)驗(yàn)條件下脫除堿金屬效果更明顯。計(jì)算結(jié)果表明,較 高的溫度有利于堿金屬的吸收。 Abstract: Active bauxite,silicon dioxide,diatomaceous earth and ash have been found suitab le for alkali removal from hot flue gas in a coal conversion system.The effect o f t emperature on the alkali adsorption/reaction using these sorbents was surveyed in the experiments in which a thermogravimetric analyzer was utilized under a simu lated flue gas condition.Equilibrium calculations were also carried ou t to dete rmine the mechanism of reaction.The results reveal that although all these sorbe nts are available for the alkali removal,the active bauxite and silicon dioxide a re more effective,and the calculations suggest that a higher temperature can take more advantage to the alkali removal. 作 者: 漢春利 張軍 顏崢 劉坤磊 徐益謙 陳逸 戴樂(lè)美 HAN Chun-li ZHANG Jun YAN Zheng LIU Kun-lei XU Yi-qian CHEN Yi-jun Dai Le-mei 作者單位: 漢春利,張軍,顏崢,劉坤磊,徐益謙,HAN Chun-li,ZHANG Jun,YAN Zheng,LIU Kun-lei,XU Yi-qian(東南大學(xué) 熱能工程研究所,)陳逸,戴樂(lè)美,CHEN Yi-jun,Dai Le-mei(南京大學(xué) 現(xiàn)代分析中心,)
