活性炭改性及其脱硫脱硝性能研究与展望

摘要/Abstract

摘要： 活性炭具有独特的孔隙结构和表面性质,这使其在净化工业烟气领域中有着重要应用。普通活性炭孔容偏小、微孔分布较宽、比表面积较小,导致其吸附性能无法较好地满足烟气深度净化需求。对活性炭进行改性可优化孔容孔径,提高孔隙率,改善表面酸碱性,进而提高活性炭的吸附性能。本文综述了近年来在酸性、碱性和中性条件下改性活性炭的研究进展,并基于活性炭改性现存的不足和瓶颈问题总结了未来活性炭改性的研究重点。

Abstract: Activated carbon has an extremely important application in the field of industrial flue gas purification due to its unique pore structure and surface properties. However, the small pore volume, wide distribution of micropores and small specific surface area of ordinary activated carbon made its adsorptive property cannot meet the needs of deep purification. The modification of activated carbon optimize its pore volume and aperture, improve its porosity and surface acidity and alkalinity, and therefore improve the adsorption performance of activated carbon. In this paper, the research progress of modified activated carbon under acidic, alkaline and neutral conditions over recent years has been summarized. And based on the existing shortcomings and bottlenecks of activated carbon modification. The research focus on activated carbon modification in the future is suggested.

Key words: activated carbon, desulfurization and denitrification, modification, pore structure, specific surface area, adsorption performance
