摘要:

煤在气化和燃烧过程中产生的气体污染物和颗粒物会转移到合成气和空气中,从而产生设备腐蚀和环境污染等问题。静电纺丝纤维具有可调控的、超细的直径,多孔的结构,超高的比表面积,可设计的形貌以及易于表面修饰等优点,在气体污染物脱除领域有着巨大的应用价值。介绍了静电纺丝的基本原理和发展现状,综述且简要分析了静电纺丝纳米纤维材料在PMs、CO2、NOx、H2S、SO2和VOCs等气体污染物脱除方面的应用及研究现状。最后,对电纺纤维在气体污染物脱除领域中更广泛、更深入的应用前景进行了展望。

Abstract:

The gaseous pollutants and particulate matters produced during coal gasification and combustion will be transferred to syngas and air, resulting in problems such as equipment corrosion and environmental pollution. Electrospun nanofibers have the advantages of controllable and ultra-fine diameter, porous structure, ultra-high specific surface area, designable morphology, and easy to be modified on the surface, and thus have great application value in gas pollutants removal. The basic principle, development history and current situation of electrospinning were introduced, and the application and research status of electrospun nanofiber materials in the removal of gas pollutants such as PMs, CO2, NOx, H2S, SO2 and VOCs were summarized and analyzed. Finally, more extensive and depth perspectives of nanofibers material synthesized by electrospinning in the applications of gas pollutants removal were also discussed and expected.

Key words: gasification, pollutant, sorbents, gas purification, electrospun fiber
