摘要:
以不同吸附材料吸附性能测试实验的结果为依据,对水涤脱附条件下活性炭同时脱硫脱硝过程的机理进行了研究,并对参与吸附过程的反应空间进行了分析.研究表明,活性炭的孔径分布是决定吸附材料对SO2和NO吸附性能的关键因素,活性炭同时吸附SO2和NO时,反应构型临界尺寸比单纯脱硫过程中的尺寸增大,直径为1.1~1.5nm的孔隙成为主要的吸附场所,平均孔径为6.27nm、微分孔径分布峰值为1.0~3.5nm的活性炭AC6成为一种具有最佳吸附性能的活性炭
Abstract:
The mechanism of the activated carbon desulfurization and denitrification is researched according to the results ofthe adsorbing performance experiments using different adsorbents.The reaction space of the adsorption process under thecondition of water desorption is analyzed.Studies show that the aperture distribution of the activated carbon is a crucialfactor in the adsorption process.When SO2and NO are adsorbed simultaneously by activated carbon,pores whose aperture is 1.1~1.5nm become primary adsorption sites.Critical sizes of the reaction configurations are larger than those ofthe simple desulfurization process.A type of good adsorbent AC6,whose average aperture is 6.27nm and peak value ofdifferential aperture is 1.0~3.5nm is brought forward.
