活性炭的表面改性及其用于液态烃吸附脱氮的研究的中期报告 摘要： 活性炭是一种良好的吸附材料，其吸附能力受到其表面性质的影响。本文研究了活性炭的表面改性，以及改性活性炭对液态烃吸附脱氮性能的影响。实验结果表明，通过表面氧化和螯合改性可以显著提高活性炭的表面羟基含量和螯合能力。在液态烃（甲苯、庚烷）吸附脱氮实验中，改性活性炭的吸附量和吸附速率均有所提高。进一步研究表明，改性活性炭的吸附性能受到氮化物种类和浓度的影响。 关键词：活性炭；表面改性；液态烃；吸附脱氮 Abstract: Activated carbon is a good adsorbent material, and its adsorption capacity is affected by its surface properties. In this paper, the surface modification of activated carbon and the effect of modified activated carbon on the adsorption and denitration performance of liquid hydrocarbons were studied. The experimental results show that the surface hydroxyl content and chelation ability of activated carbon can be significantly improved by surface oxidation and chelation modification. In the adsorption and denitration experiments of liquid hydrocarbons (toluene, n-hexane), the adsorption capacity and rate of modified activated carbon were improved. Further study shows that the adsorption performance of modified activated carbon is affected by the type and concentration of nitride. Keywords: activated carbon; surface modification; liquid hydrocarbon; adsorption, denitration
