| 中文摘要: |
| 對一種椰殼活性炭對甲基丙烯酸甲酯的吸附消除行為進行了研究，重點考察了甲基丙烯酸甲酯的濃度、流速和吸附溫度等條件以及水汽存在時對活性炭吸附行為的影響。結果表明，該顆粒活性炭對甲基丙烯酸甲酯有良好的吸附效果，甲基丙烯酸甲酯進口濃度和進氣量的改變均會影響吸附飽和時間，導致其增加或減少。通過變溫吸附實驗確定降低環境溫度對其吸附有促進作用。濕度為50%時吸附量相對干氣飽和吸附量影響較小，說明該活性炭抗水汽能力較好。經多次重復再生實驗，其飽和吸附量未見明顯下降。 |
| 英文摘要: |
| The adsorption of methyl methacrylate (MMA) on a coconut shell activated carbon (CSAC) was studied， and the effects of concentration， flow velocity， adsorption temperature and water vapor precondition which acted on the performance of VOCs adsorption were discussed. The results illustrated that the CSAC had a good capability of adsorbing MMA. With changing of MMA inlet concentration and quantity， the time of adsorption equilibrium would move forward or backward. Temperature swing adsorption experiment proved that reducing temperature would promote the adsorption performance of the CSAC. When the humidity was 50%， the adsorption behavior of the CSAC was not influenced obviousely， which indicated that the activated carbon had a good hydrophobicity. Coconut shell activated carbon was regenerated for many times， it still could remain its good capacity of adsorption. |
