硫化氢深度吸附材料的研究进展

Research progress of hydrogen sulfide deep adsorption materials

目前硫化氢(H2S)日益成为制约工业化发展的一个重要因素,即使在较低的浓度下仍会破坏环境、腐蚀设备。如何能将含硫气体清洁、高效、深度脱除已成为国内外学者的研究重点。吸附法脱硫以其脱硫程度高、高效环保、操作简单和吸附剂可重复利用等优点具有良好的发展前景。研制一种选择性好、吸附容量大、性能稳定、再生性好的吸附剂是吸附法脱硫的关键。本文以深度脱除H2S为目标,综述了碳基材料、多孔金属氧化物、沸石分子筛、金属有机框架(MOFs)等几种不同吸附材料的研究进展,总结深度脱硫今后的发展方向,旨在为后续的研究提供借鉴。

At present,hydrogen sulfide(H2S)has increasingly become an important factor restricting the development of industrialization.Even at a low concentration,it will still damage the environment and corrode equipment.The deep purification of sulfur-containing gas by using an environmental and efficient method has gained the attention of researchers on domestic and overseas.Adsorption desulfurization has a good prospective because of its deep removal,high efficiency,environmental-friendly performance and good regeneration.The key of adsorption desulfurization is to develop an adsorbent with good selectivity,large adsorption capacity,stable performance and good reproducibility.This paper summarizes the recent advances in several adsorbent materials such as carbon-based materials,porous metal oxides,zeolite and metal-organic frameworks(MOFs),making a comment on the future development directions of deep removal of H2S,aiming at providing a reference for further research.
